Description

This product consists of two fluorochrome-conjugated monoclonal antibodies to distinguish human peripheral CD3⁺ T cells and CD19⁺ B cells. The UCHT1 monoclonal antibody (mouse IgG1, κ, HLDA #III471) reacts with human CD3e, a 20 kDa subunit of the TCR complex. Along with the other CD3 subunits γ and δ, the ε chain is required for proper assembly, trafficking and surface expression of the TCR complex. CD3 is expressed by thymocytes in a developmentally regulated manner and by all mature T cells. The HIB19 monoclonal antibody (mouse IgG1, κ, HLDA #VCD19.11) reacts with human CD19, a 95 kDa transmembrane glycoprotein. CD19 is expressed by B cells during all stages of development excluding the terminally differentiated plasma cells. Follicular dendritic cells also express CD19. Together CD21, CD81, Leu13, MHC class II, and CD19 form a multimolecular complex that associates with BCR. Signaling through CD19 induces tyrosine phosphorylation, calcium flux and proliferation of B cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The product is formulated for use in two-color analysis by flow cytometric analysis.

Applications Tested

This lot has been pre-titrated, mixed and tested by flow cytometric analysis of human peripheral blood leukocytes and can be used at 20 μl per 100μl blood (or per 1 million cells in 100 μl total staining volume).
