Product Description

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.
Allophycocyanin (APC) is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 650 nm and an emission maximum (Em Max) at 660 nm. APC is designed to be excited by the Red (627-640 nm) laser and detected using an optical filter centered near 660 nm (e.g., a 660/20 nm bandpass filter).

Conjugation:
Purified antibody is conjugated with APC 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.
