Description

PA007522.h1: Recombinant Anti-biotin Antibody, Human IgG1 Kappa

Anti-biotin antibody is an antibody that specifically binds to biotin, a small vitamin (vitamin B7) involved in various metabolic processes. These antibodies are typically raised in animals (e.g., rabbits, goats, or mice) by immunizing them with biotin conjugated to a carrier protein, as biotin alone is too small to elicit a strong immune response.

Anti-biotin antibodies are widely used in research and biotechnology, particularly in techniques like ELISA, Western blotting, or immunohistochemistry, where biotin’s strong affinity for proteins like streptavidin or avidin is exploited. For example, a biotinylated molecule (e.g., a protein or nucleic acid tagged with biotin) can be detected or captured using an anti-biotin antibody, which may be conjugated to a reporter molecule (like an enzyme or fluorophore) for visualization or quantification.

In essence, anti-biotin antibodies serve as tools to detect or manipulate biotin-tagged molecules in various experimental setups.

The in vivo grade recombinant anti-biotin antibody (human IgG1 kappa) of Syd Labs was produced in mammalian cells.

“Udeshi et al. developed a method using an anti-biotin antibody to enrich biotinylated peptides, as published in Nature Methods. …The anti-biotin antibody is a good capture reagent for biotinylated peptides because of its relatively low binding affinity to biotin, which thereby ensures high recovery via increase in elution efficiency. …The approach involved developing a monoclonal anti-biotin antibody with better reproducibility as compared to existing polyclonal antibodies (pAbs). …A monoclonal anti-biotin antibody was developed at CST using a standard antibody development pipeline. …Samples were incubated with anti-biotin antibody beads for 1 h at 4 °C.”

“Anti-biotin antibody-HRP and avidin-HRP were purchased from Sigma-Aldrich (St Louis, MO, USA), biotin (S)-sulfoxide and lidimycin were purchased from TopScience (Shanghai, China), and 96-well ELISA plates were purchased from Corning (USA). …The failure to develop sandwich ELISA for small molecules is not directly caused by their molecular weight but largely by the steric hindrance caused by the small distance between epitopes. …In the present study, a new derivatizing agent was prepared by coupling o-nitrobenzaldehyde and biotin with spacer arms, and two sandwich ELISA modes were established for detecting the small molecule compound SEM, namely, double-antibody sandwich and antibody-avidin sandwich. …A sandwich ELISA method was developed for SEM based on anti-SEM-NBA antibody and avidin. …Under the distances, the sensitivities of the sandwich ELISA were no lower than those of competitive ELISA.”

“Cy3B560 was conjugated with the secondary antibodies, staining anti-biotin primary antibodies, while biotin was abundantly inserted into the 7S DNA hybridization probe for mtFISH. …These are co-localized with red small spheres/points, indicating localizations of the ATP6-COX3 gene region which was target of the ATP6COX-biotin 1,100 bp hybridization probe with the directly inserted biotin, which was visualized by anti-biotin Cy3B-immunostaining. …This mtFISH probe was visualized by anti-biotin primary Ab followed by Cy3B-560-conjugates secondary antibodies (“ATP6COX-biotin-Cy3B”) (Fig. 1b). …The average photon count from a single signal detected and localized was 400. The average number of events per frame was 6.2. Imaging of Cy3B preceded imaging with A647. …Routinely, only nucleoids constructed from more than 10 localized A647 (Cy3B) fluorophores were considered in each image.”

“Excess anti-biotin-PE was removed by washing the labeled bPS-beads three times. …Aggregation of the bead particles on the side of the tube allowed for easy supernatant aspiration. …The ratio of bPS-beads to anti-biotin-PE was tested in a stepwise manner at v/v ratios of: 50:0.5, 50:1, 50:2, 50:4, and 50:8 for each pneumococcal serotype. …The bead-based Ag-specific B cell quantitation method was compared with unbound bPS detected directly with anti-biotin-PE without the involvement of beads. …PBMCs were incubated with the mAbs combination described above, the bPS monomer, and anti-biotin-PE.”

“In this strategy, the primary amine groups of lysines on proteins on the surface of live cells are first labeled with biotin, and subsequently, biotinylated peptides are enriched by anti-biotin antibodies and analyzed by liquid chromatography–tandem mass spectrometry (LC–MS/MS). …Following cell lysis and proteolytic digestion, biotinylated peptides were enriched using our previously published protocol which employs bead-immobilized anti-biotin antibodies. …Proteins were harvested and digested prior to enrichment of biotinylated peptides using anti-biotin antibodies for LC–MS/MS analysis. …We have developed sBioSITe—a novel method to enrich surface proteins by labeling them with biotin followed by enrichment at the peptide level using anti-biotin antibodies, and detection of peptides with intact biotin tags. …Our strategy combined the use of a non-cleavable biotinylation reagent with enrichment using anti-biotin antibodies, enabling us to detect peptides with biotin tags intact.”
