Barnhill, Hannah N. published the artcileDual modification of turnip yellow mosaic virus: synthesis of a biotinylated luminescent nanoparticle, Quality Control of 359860-27-8, the publication is PMSE Preprints (2006), 379-380, database is CAplus.

In this study, turnip yellow mosaic virus (TYMV) was employed as a scaffold for creating a bi-functional nanoparticle. TYMV is a 30 nm icosohedral virus with 60 asym. units and 180 protein subunits. As a proof concept that TYMV can be used as a multifunctional nanoparticle, luminescent metal complexes and the bio-active mol. biotin was conjugated onto the surface of TYMV using traditional bioconjugation methods. This study showed that the particle retains its integrity after the reaction and is stable to the attached functional groups. In addition, the two functional groups still retain their properties and can interact with each other on the surface as demonstrated by fluorescence resonance energy transfer.

Reverse chem. proteomics using T7 phage display is a powerful technique for identifying cellular receptors of biol. active small mols. However, to date this method has generally been limited to cDNA libraries constructed from mRNA isolated from eukaryotes. In this paper, the authors describe the construction of the first prokaryotic T7 phage display libraries from randomly digested Pseudomonas stutzeri and Vibrio fischeri gDNA, as well as a plant cDNA library from Arabidopsis thaliana. The authors also describe the use of T7 phage display to identify novel proteins from environmental DNA samples using biotinylated FK506 as a model affinity probe.

The development of fluorinated sulfone derivatives as versatile electrophiles for Suzuki-Miyaura cross-coupling reactions is described. Introducing electron-withdrawing groups on the aryl ring of the sulfone facilitates the Pd-catalyzed activation of the C-SO₂ bonds. Cross-coupling reactions with fluorinated sulfone electrophiles are reported, leading to a variety of multiply arylated products in good yields. The reactivity of this unusual electrophile is benchmarked vs. common electrophiles and its use in iterative cross-couplings for concise synthesis of biol. active mols. is described.

Akkahat, Piyaporn published the artcileDevelopment of a Novel Antifouling Platform for Biosensing Probe Immobilization from Methacryloyloxyethyl Phosphorylcholine-Containing Copolymer Brushes, Name: N-(2-(2-(2-(2-Aminoethoxy)ethoxy)ethoxy)ethyl)-5-((3aS,4S,6aR)-2-oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl)pentanamide, the publication is Langmuir (2012), 28(13), 5872-5881, database is CAplus and MEDLINE.

The immobilization of thiol-terminated poly[(methacrylic acid)-ran-(2-methacryloyloxyethyl phosphorylcholine)] (PMAMPC-SH) brushes on gold-coated surface plasmon resonance (SPR) chips was performed using the grafting to approach via self-assembly formation. The copolymer brushes provide both functionalizability and antifouling characteristics, desirable features mandatorily required for the development of an effective platform for probe immobilization in biosensing applications. The carboxyl groups from the methacrylic acid (MA) units were employed for attaching active biomols. that can act as sensing probes for biospecific detection of target mols., whereas the 2-methacryloyloxyethyl phosphorylcholine (MPC) units were introduced to suppress unwanted nonspecific adsorption. The detection efficiency of the biotin-immobilized PMAMPC brushes with the target mol., avidin (AVD), was evaluated in blood plasma in comparison with the conventional 2D monolayer of 11-mercaptoundecanoic acid (MUA) and homopolymer brushes of poly(methacrylic acid) (PMA) also immobilized with biotin using the SPR technique. Copolymer brushes with 79 mol % MPC composition and a mol. weight of 49.3 kDa yielded the platform for probe immobilization with the best performance considering its high S/N ratio as compared with platforms based on MUA and PMA brushes. In addition, the detection limit for detecting AVD in blood plasma solution is 1.5 nM (equivalent to 100 ng/mL). The results demonstrated the potential for using these newly developed surface-attached PMAMPC brushes for probe immobilization and subsequent detection of designated target mols. in complex matrixes such as blood plasma and clin. samples.

Jeong, Jae Hyun published the artcileA novel immobilization technique using a poly(amino acid) multilayer designed for surface plasmon resonance sensing, HPLC of Formula: 359860-27-8, the publication is Chemical Physics Letters (2006), 421(4-6), 373-377, database is CAplus.

The novel immobilization technique using a poly(amino acid) multilayer was designed for the SPR sensing platform. The poly(amino acid) multilayer was confirmed as a relatively hydrophilic surface with little tendency for nonspecific adsorption of biomols. and a flat surface that the biomol. interactions can occur uniformly on the sensing surface. The poly(amino acid) multilayer functionalized with biotin was investigated to control the surface d. and to estimate the optimum space between ligands for effective SPR sensing. This multilayer study demonstrates the importance of surface d. which is significantly sensitive for fabrication of surface functional group in the monitoring of kinetic phenomena.

Lee, Bong Soo published the artcileFormation of activation-free, selectively bioconjugatable poly(N-acryloxysuccinimide-co-oligoethylene glycol methyl ether methacrylate) films by surface-initiated ARGET ATRP, Recommanded Product: N-(2-(2-(2-(2-Aminoethoxy)ethoxy)ethoxy)ethyl)-5-((3aS,4S,6aR)-2-oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl)pentanamide, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2017), 55(2), 329-337, database is CAplus.

Activation-free copolymeric films possessing high selectivity to target proteins and low biofouling background are prepared via controlled radical polymerization The copolymeric films are generated by surface-initiated activators regenerated by electron transfer atom transfer radical polymerization (SI-ARGET ATRP) of N-acryloxysuccinimide (NAS) and oligo(ethylene glycol) Me ether methacrylate (OEGMEMA) by controlling the molar feed ratio of the two monomers. The formation of copolymeric films is characterized by ellipsometry, contact angle goniometry, FTIR spectroscopy, and XPS. The prepared copolymeric films are biotinylated without an activation step. Biotin-streptavidin association is employed as a model system to investigate both selective binding and the relevant signal-to-noise (S/N) ratio. When the molar feed ratio of NAS and OEGMEMA is 2:8, the copolymeric film is optimized to give the highest S/N ratio (339.8) according to surface plasmon resonance studies. The highly selective bioconjugation is used to generate micropatterns of rhodamine-conjugated streptavidin on the copolymeric film. © 2016 Wiley Periodicals, Inc.J. Polym.

Yu, Hye-Weon published the artcileMultiplex competitive microbead-based flow cytometric immunoassay using quantum dot fluorescent labels, Quality Control of 359860-27-8, the publication is Analytica Chimica Acta (2012), 191-198, database is CAplus and MEDLINE.

The simultaneous anal. of environmental hazards, microcarrier-based multiplex technologies show great promise. Further integration with biofunctionalized quantum dots (QDs) creates new opportunities to extend the capabilities of multicolor flow cytometry with their unique fluorescence properties. We developed a competitive microbead-based flow cytometric immunoassay using QDs fluorescent labels for simultaneous detection of 2 analytes, bringing the benefits of sensitive, rapid and easy-of-manipulation anal. tool for environmental contaminants. As model target compounds, the cyanobacterial toxin microcystin-LR and the polycyclic aromatic hydrocarbon compound benzo[a]pyrene were selected. The assay was carried out in 2 steps: the competitive immunol. reaction of multiple targets using their exclusive sensing elements of QD/antibody detection probes and antigen-coated microsphere, and the subsequent flow cytometric anal. The fluorescence of the QD-encoded microsphere was thus found to be inversely proportional to target analyte concentration Under optimized conditions, the proposed assay performed well within 30 min for the identification and quant. anal. of the 2 contaminants. For microcystin-LR and benzo[a]pyrene, dose-response curves with IC₅₀ values of 5 and 1.1 μg/L and dynamic ranges of 0.52-30 and 0.13-10 μg/L were obtained, resp. Recovery was 92.6-106.5% for 5 types of water samples (bottled water, tap water, surface water and seawater) using only filtration as sample pretreatment.

We successfully fabricated poly(ethylene terephthalate) (PET) surfaces through a perfluoroaryl azide-based photochem. reaction, and subsequently formed an intrinsically activated, non-biofouling poly[N-acryloxysuccinimide-co-oligo(ethylene glycol) Me ether methacrylate] on the surface through surface-initiated, controlled radical polymerization The grafted copolymer film on PET facilely generated a protein pattern using a microcontact printing technique without employing both an activation step to introduce an active functional group (e.g., succinimidyl ester) and a passivation process for minimizing non-specific adsorption. Consequently, we characterized the functionalized PET surfaces by using various methods including contact angle measurement, XPS, scanning probe microscopy (SPM), field-emission SEM (FE-SEM). In addition, we evaluated the non-biofouling efficacy of the protein-patterned copolymer film on PET by confocal laser scanning microscopy.[Figure not available: see fulltext.].
