| Background | Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation. provided by RefSeq, Jul 2008 |

AI Summary: OriGene’s purified anti-CD19 monoclonal antibody (Cat# UM500071) was used as a comparator in immunohistochemistry experiments to evaluate the detection capabilities of newly developed anti-Whitlow antibodies for identifying CAR T cells in tissue samples.
Snippet: and baked at 60°C for 1 hour. For single-marker IHC, antigen retrieval was performed using Tris-EDTA buffer, pH 9 (Abcam, Cat# ab93684), at 95°C for 20 min. Purified anti-Whitlow or anti-CD19 (Origene #UM500071) mAbs were applied using an intelliPATH Stainer (Biocare Medical), followed by anti-mouse Fc secondary detection, visualization with 3,3′-diaminobenzidine chromogen, and hematoxyli
