CD3 epsilon Antibody

• Catalog Number: orb640028
• Category: Antibodies
• Description: Recognizes the epsilon-chain of CD3, which consists of five different polypeptide chains (designated as gamma, delta, epsilon, zeta, and eta) with MW ranging from 16-28kDa. The CD3 complex is closely associated at the lymphocyte cell surface with the T cell antigen receptor (TCR). Reportedly, CD3 complex is involved in signal transduction to the T cell interior following antigen recognition. The CD3 antigen is first detectable in early thymocytes and probably represents one of the earliest signs of commitment to the T cell lineage. In cortical thymocytes, CD3 is predominantly intra-cytoplasmic. However, in medullary thymocytes, it appears on the T cell surface. CD3 antigen is a highly specific marker for T cells, and is present in majority of T cell neoplasms.

IHC staining of FFPE human spleen with recombinant CD3e antibody (clone rC3e/1931). HIER: boil tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min and allow to cool before testing.

Analysis of HuProt (TM) microarray containing more than 19000 full-length human proteins using recombinant CD3e antibody (clone rC3e/1931). These results demonstrate the foremost specificity of the rC3e/1931 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt (TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt (TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.

SDS-PAGE analysis of purified, BSA-free recombinant CD3e antibody (clone rC3e/1931) as confirmation of integrity and purity.

IHC staining of FFPE human tonsil with recombinant CD3e antibody (clone rC3e/1931). HIER: boil tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min and allow to cool before testing. Negative control inset: PBS used instead of primary antibody to control for secondary Ab binding.
