Biolegend, 116403, Biotin anti-mouse I-A, 50μg

The AF6-120.1 antibody reacts with the I-A b MHC class II alloantigen. These class II molecules are expressed on antigen presenting cells (including B cells) and a subset of T cells from H-2 b bearing mice, and are involved in antigen presentation to T cells expressing CD3/TCR and CD4 proteins. The AF6-120.1 antibody cross-reacts with H-2 k and H-2 u haplotypes; this antibody does not cross-react with other haplotypes (d, f, q, r, s).
50μg
Verified Reactivity: Mouse
Antibody Type: Monoclonal
Host Species: Mouse
Immunogen: C57BL/10J splenocytes
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography, and conjugated with biotin under optimal conditions.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.
Application: FC - Quality tested
Recommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes: Additional reported applications (for relevant formats of this clone) include: immunohistochemical staining of frozen sections (acetone-fixed5; OCT-embedded, ethanol-fixed sections7), immunofluorescence microscopy3 (including acetone-fixed epidermal sheets6), immunoprecipitation7,8. Directly conjugated antibody was used for IF in (3) and (6) and for IHC in (5). Does not react with other haplotypes (e.g., d, f, q, r, s).

Q: How many biotin molecules are per antibody structure?
A: We don't routinely measure the number of biotins with our antibody products but the number of biotin molecules range from 3-6 molecules per antibody.
