Description

Product Name:Anti-Human CD2 (LO-CD2a) In Vivo Antibody - Low Endotoxin
Product Code:IVMB0262
Size:1 mg, 5 mg, 25 mg, 50 mg, 100 mg
Clone:LO-CD2a
Protein:CD2
Product Type:Hybridoma Monoclonal Antibody
Synonyms:LFA-2, T11, SRBC, BTI-322
Isotype:Rat IgG2b k
Reactivity:Human
Applications:ELISA, FA, FC, In Vivo
Formulation:This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.
Endotoxin Level:< 1.0 EU/mg as determined by the LAL method
Purity:≥95% monomer by analytical SEC ⋅ >95% by SDS Page
Product Preparation:Functional grade preclinical antibodies are manufactured in an animal free facility using in vitro cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
Applications:ELISA, FA, FC, In Vivo
Reactivity:Human
Host Species:Rat
Specificity:Anti-CD2 antibody (clone LO-CD2a) activity is directed against human CD2.
Antigen Distribution:CD2 is expressed on all mature human T cells, most thymocytes, NK cells and a small proportion of bone marrow cells.
Immunogen:purified human T Lymphocytes
Concentration:≥ 5.0 mg/ml
Endotoxin Level:< 1.0 EU/mg as determined by the LAL method

Storage and Handling:Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -70°C. Avoid Repeated Freeze Thaw Cycles.

Human CD2 is a 351 amino acid transmembrane glycoprotein that is part of the immunoglobulin superfamily1, 2. CD2 is expressed on the surface of mature T cells, most NK cells, thymocytes, dendritic cells, and 9-12% of bone marrow cells. CD2 participates in T cell and NK cell activation and is important for thymocyte development and assembly of the immunological synapse1. However, the role of CD2 in murine immunity is not always consistent with its function in higher animals. CD2 is known to bind to lymphocyte-associated antigen3 (CD58 and its murine analog CD48) as well as CD59.

LO-CD2a was developed as an immunosuppressive agent for use in organ allotransplantation3, 4. LO-CD2a strongly inhibits mixed lymphocyte culture3 and induces T cell apoptosis5. Additionally, LO-CD2a induces very low levels of cytokine release, inhibits cytokine production induced by OKT3, and induces human T cell hyporesponsiveness3. The immune response is inhibited as a result of cell lysis by antibody-dependent cell mediated cytotoxicity (ADCC) induced by NK cells and activated monocytes and from CD2 down-modulation on CD2+ cells6. LO-CD2a also strongly inhibits proliferation of peripheral blood mononuclear cells stimulated with soluble OKT3. LO-CD2a has demonstrated immunosuppressive activity in vitro and effective T cell depletion in vivo. Unresponsiveness upon restimulation with the same antigen makes LO-CD2 distinct from other anti-CD2 antibodies7.
