Monoclonal Anti-Biotin (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Biotin is an essential vitamin required by cells in living organisms or in cultures. An immunoglobulin has two heavy chain and two light chain connected by disulfide bond. It is a glycoprotein. IgG is a major class of immunoglobulin.
The antibody recognizes free biotin and biocytin using competitive ELISA. Using indirect ELISA or immunohistochemical staining, the antibody also recognizes biotin conjugated to various immunoglobulins. Specificity is evaluated using biotinylated goat antibodies to human and rabbit antigens coated on multiwell plates.
Immunogen
Biotin-KLH conjugate
Application
May be substituted for avidin to decrease non-specific binding.
Monoclonal Anti-Biotin-FITC antibody produced in mouse has been used in the localization of the antigen with a primary antibody, addition of a biotinylated antibody to bind to primary antibody and finally application avidin-FITC.
The antibody may be used in amplification techniques, ELISA, immunoblotting, in situ nucleic acid hybridization, flow cytometry, image analysis or confocal microscopy. In some applications, localization of biotinylated probes with avidin produces high background levels. Anti-biotin reagents may be substituted for avidin to decrease non-specific binding.
Biochem/physiol Actions
An immunoglobulin mainly helps in immune defense. Immunoglobulin G (IgG) participates in hypersensitivity type II and type III.
Physical form
Solution in phosphate buffered saline, pH 8.0, containing 1% bovine serum albumin and 15 mM sodium azide.

Despite the preferential localization of CD4 to lipid rafts, the significance and role of these microdomains in HIV-1 entry is still controversial. The possibility that CD4, when localized to non-raft domains, might be able to support virus entry cannot be

Nanoparticle platforms are being intensively investigated for neurological applications. Current biological models used to identify clinically relevant materials have major limitations, e.g. technical/ethical issues with live animal experimentation, failure to replicate neural cell diversity, limited control over cellular stoichiometries and
