Background:
The recombinant monoclonal antibody specifically binds to CD20, encoded by the MS4A1 (Membrane-spanning 4-domains, subfamily A, member 1) gene. CD20 is a 33-37kDa, unglycosylated four-transmembrane phosphoprotein. CD20 is expressed on pre-B-cells, resting and activated B cells, and follicular dendritic cells, but not plasma cells. Low level CD20 expression is observed on a small subset of normal circulating T lymphocytes. The CD20 molecule is involved in the regulation of B-cell activation and proliferation.
PerCP conjugates are excited by the 488 nm line of the argon-ion laser and have a large Stokes shift, providing minimal spectral overlap into the R-PE (phycoerythrin) channel.
Conjugation:
Purified antibody is conjugated with PerCP under optimum conditions. The conjugate is purified by size-exclusion chromatography and adjusted for direct use.
Recommended Usage:
Each lot of this antibody is quality control tested by flow cytometric analysis. The amount of the reagent is suggested to be used 10 µL of antibody per test (million cells in 100 µL staining volume ). Since applications vary, the appropriate dilutions must be determined for individual use.
