Bulk anti-CD3 In Vivo Antibody – Low Endotoxin (UCHT-1)
ichorbio’s anti-CD3 In Vivo Antibody – Low Endotoxin (UCHT-1) is manufactured in a cGMP compliant, ISO Quality Standard 9001:2015 facility. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio offers Amazon vouchers or donations to the NC3Rs for reviews of this product: click here for more information. ichorbio: the best antibodies for in vivo research.
Anti-CD3 In Vivo Antibody – Low Endotoxin (UCHT-1) recognizes Human CD3. anti-Human CD3 recognizes a (Mr 22-28 kDa) T-cell surface glycoprotein. The epitope recognized by the CD3 antibody is expressed on a constant region of the epsilon chain of the CD3 antigen/T-cell receptor complex (TCR)
This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
The CD3 antigen is expressed on approximately 60-80% of human peripheral blood lymphocytes, 20-40% of splenic lymphocytes, the majority of T-CLL and approximately 70% of T-ALL Cells.
Anti-CD3 may be used for enumerating immunocompetent T-lymphocytes in peripheral blood. Clone UCHT-1 is also useful in histology for localization of T-lymphocytes in tissue and may be used to enrich T-cells by cell sorting. This T-cell marker has also been used to determine T-versus B-cell lymphomas and leukemias. The UCHT-1 clone is recognized in the human leukocyte differentiation antigen workshop III 471.

anti-CD3 In Vivo Antibody – Low Endotoxin (UCHT-1) is stable for at least one week when stored sterile at 2-8°C. For long term storage aseptically aliquot in working volumes without diluting and store at –80°C. Avoid Repeated Freeze Thaw Cycles.
Flow Cytometry, Immunoprecipitation, Western Blot
Flow Cytometry: It is recommended to use the indirect method for signal enhancement when enumerating cells expressing CD3. A suggested method would be to stain cells expressing CD3 with 2.0 µg per million cells in a total staining volume of 100 µl followed by Goat Anti-Mouse IgG (H&L)-R-phycoerythrin.
Each investigator should determine their own optimal working dilution for specific applications.
