Description
The GOT214A monoclonal antibody specifically binds to mouse CD20, also known as B-lymphocyte antigen and Bp35. CD20, a member of the MS4A gene family, is a 33-37 kDa protein comprised of four transmembrane spanning regions that present as a homo-oligomeric complexes on the cell surface. CD20 is expressed on most mature B cells but not on plasma cells. During development, CD20 is initially expressed after the induction of CD19 and is co-expressed with IgM during the pre-B to immature B cell transition in bone marrow. Expression of CD20 increases during maturation with almost all mature B cells expressing CD20 at some level. Unlike other B cell antigens, CD20 is not shed or internalized upon antibody binding. CD20 regulates B-cell activation and proliferation. Its ligation promotes transmembrane Ca2+ trafficking.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
5. An isotype control should be used at the same concentration as the antibody of interest.
6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
