Long descriptionIntegrin, alpha L (antigen CD11A (p180), lymphocyte function-associated antigen 1; alpha polypeptide), also known as ITGAL, is a Human gene which functions in the immune system. It is involved in cellular adhesion and costimulatory signaling. ITGAL encodes the integrin alpha L chain. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This I-domain containing alpha integrin combines with the beta 2 chain (ITGB2) to form the integrin lymphocyte function-associated antigen-1 (LFA-1), which is expressed on all leukocytes. LFA-1 is part of the family of leukocyte integrins that are recognised by their common β-chains (CD18). LFA-1 also has a distinct α-chain (CD11a). LFA-1 is expressed on lymphocytes, monocytes and granulocytes; it has been shown that LFA-1 contributes to the adhesion reaction of these cells. Blocking experiments with anti-LFA monoclonal antibodies demonstRated that LFA-1 inhibits the adhesion step effector and target cells in cytotoxic T lymphocyte, natural killer and lectin dependent cytotoxicity. LFA-1 is involved in recruitment to the site of infection. It binds to ICAM-1 on antigen-presenting cells and functions as an adhesion molecule. LFA-1 is the first to bind T-cells to antigen-presenting cells and initially binds weakly. A signal from the T-cell receptor and/or the cytokine receptor changes the conformation and prolongs the cell contact, allowing the T-cell to prolifeRate. A unique antibody NKI(SPV)-L16, reacting with the a-chain of the Human leukocyte function-associated Ag- 1 (LFA- 1) has been made available. This antibody stimulates homotypic cell-cell interactions in a manner very similar to 12-0-tetradecanoyl-phorbol1-3 -acetate (TPA), in contrast to other anti-LFA-1 mAb which inhibit cell aggregation. Immunoprecipitation and enzyme digestion studies revealed that NKI-L16 recognizes a unique epitope on the cy-chain of LFA-1,most likely situated close to the transmembrane segment of the molecule. It is hypothesized that NKI-L16 or TPA can cause the LFA-1 molecule to convert from an inactive to an active configuRation, thereby permitting binding of LFA-1 1 to its natural ligand. This mAb directed, in contrast to other anti-LFA-1 antibodies, stimulates Rather than inhibits homotypic cell aggregate formation, but does not affect cell prolifeRation.
Antibody come fromThe antibody was raised by immunization of Balb/c mice with monocytes. The unique activation dependent epitope of the SPV-L16 antibody on the a-chain of LFA-1 is relatively insensitive to trypsin treatment and thus most likely loCated close to the transmembrane segment of the protein.

DescriptionThis antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.
TestMouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.
