Antigen Preparation
A synthetic peptide corresponding to C-terminus of human CD20 protein.
Background
"CD20, a non-glycosylated protein, belongs to a member of the membrane-spanning 4A gene family. The molecular weight is at a range of ~34-37kDa depending on the degree of the protein phosphorylation. The CD20 antigen is present on human pre B lymphocytes and B lymphocytes at all stages of maturation. Thus, it plays an important role in the development and differentiation of B-cells into plasma cells. Low level of CD20 expression appears on normal T lymphocytes. Combination of chemo and humanized CD20 antibodies has been reported in clinical study of lymphoma diseases."
PURIFICATION
The Rabbit IgG is purified by Epitope Affinity Purification
