Recombinant T Cell Receptor antibody

Catalog No. ABIN7543145

Product Details

Target: T Cell Receptor

Antibody Type: Recombinant Antibody

Reactivity: Human

Host: Rabbit

Clonality: Chimeric

Conjugate: Un-conjugated

Application: Flow Cytometry (FACS), Immunoprecipitation (IP), Immunofluorescence (IF), Blocking Reagent (BR)

Purpose: Anti-TCR [BMA031], Rabbit IgG, kappa

Specificity: This antibody reacts with surface receptors on all alpha-beta TCR bearing cells, but does not react with receptors on gamma-delta T cells. TCR-αβ is expressed by the majority of mature CD3+ T cells.

Characteristics:

Original Species of Ab: Mouse

Original Format of Ab: IgG2b

Purification: Protein A affinity purified

Immunogen: The original antibody was generated by immunizing mice with human perihperal blood T-lymphocytes.

Clone: BMA031

Isotype: IgG kappa

Application Details

Application Notes: This antibody is recomended for detection of viable human αβ+ TCR lymphocyte. It is highly effective in modulating immune reactions and is capable of activating human T lymphocytes in vito (PMID: 3092794). Double immunofluorescence staining was used to ascertain that this antibody does not cross react with γδ+ TCR cells. FACS analysis confirmed that BMA031 did not react with γδ+ TCR cells. BMA031 successfully precipitates TCR αβ/CDR complex (PMID: 1704361). BMA031 in conjugation with triple drug induction treatment in kidney-transplanted patients showed no side effects and reduction in graft rejections (PMID: 2978369). A clinical phase II trial administered 50 mg of murine anti-human alpha/beta-TCR mAb (BMA 031) intravenously on the day of, as well as 2 and 4 days after, cadaveric donor renal transplantation in combination with a CsA/prednisone regimen. After a minimum of 30 months follow-up, the actual allograft survival rate was 87 % in the BMA-treated group compared with 68 % in the control cohort (PMID: 8009591).Humanized version of this antibody BMA 031-EUCIV3 is found to have 2.5 times less affinity than its murine parent, however the ability to cause antibody dependent cell-mediated cytolysis was significantly enhanced (PMID: 1836485).

Comment:

This chimeric rabbit antibody was made using the variable domain sequences of the original Mouse IgG2b format, for improved compatibility with existing reagents, assays and techniques.
