Description Clone REA543 recognizes the cytoplasmic domain of the human CD20 antigen, a non-glycosylated transmembrane protein of 33–37 kDa that is expressed on B lineage cells from the pre–B cell stage to the B cell lymphoblast stage. The antigen is further expressed on most malignant B cells. CD20 is not found on early B cell progenitors or plasma cells. Oligomers of CD20 form a Ca 2)+ channel and might function in the regulation of local responses during B cell activation. In vitro effects of CD20-specific antibodies on resting B cells indicate that CD20 is able to transduce an extracellular signal affecting the G0/G1 cell cycle transition. Studies have demonstrated that CD20-initiated intracellular signals involve tyrosine kinase activation and that CD20 is tightly associated with both serine and tyrosine kinases. | Additional information: Clone REA543 displays negligible binding to Fc receptors. | |
About CD20 and PerCP-Vio700
CD20 This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. This gene encodes a B-lymphocyte surface molecule which plays a role in the development and differentiation of B-cells into plasma cells. This family member is localized to 11q12, among a cluster of family members. Alternative splicing of this gene results in two transcript variants which encode the same protein.

PerCP-Vio700 PerCP-Vio® 770 is a far-red-emitting tandem fluorophore that combines PerCP and a Vio®770 dye. The donor, PerCP, can be excited by the 488 nm blue laser and transfers energy to the acceptor, Vio®770, which emits light that can be captured with a 780/60 nm bandpass filter. APC-Vio®770 has an excitation peak at 482 nm and an emission peak at 704 nm, and is spectrally similar to PerCP-Cy5.5 and PerCP-eF710. PerCP-Vio®770 is known to be very bright and photostable, as well as being stable when treated with fixatives. These favorable characteristics that make it useful in multiple different applications such as flow cytometry and Fluorescence Microscopy. The large stokes shift can be advantageous when trying to fit more colors into a multicolor panel. The Vio® dye family are products of Miltenyi Biotec, with many antibody conjugates designed and validated for flow cytometry.
