CD19 Recombinant antibody, PBS Only

• 

  WB analysis using 86116-1-RR (same clone as 86116-1-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 89985-2-RR (CD19 antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 86116-1-PBS in a different storage buffer formulation.

• 

  IHC staining of human tonsil using 86116-1-RR (same clone as 86116-1-PBS)

  Immunohistochemical analysis of paraffin-embedded human tonsil tissue slide using 86116-1-RR (CD19 antibody) at dilution of 1:1000 (under 10x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 86116-1-PBS in a different storage buffer formulation.

Background Information

CD19 is a 95 kDa type I transmembrane glycoprotein belonging to the immunoglobulin superfamily (PMID: 2472450). It is expressed by B cells and follicular dendritic cells. CD19 is up-regulated at the step of B-lineage commitment during the differentiation of the hematopoietic stem cell, it remains on during subsequent stages of differentiation until finally down-regulated during terminal differentiation into plasma cells (PMID: 8528044). CD19 is involved in B cell development, activation and differentiation. It is the dominant component for the signaling complex on B cells that includes CD21 (CR2), CD81 (TAPA-1) and CD225 and acts as a critical co-receptor for BCR signal transduction (PMID: 23210908).
