Long description
Integrins are transmembrane glycoproteins that belong to the family of adhesion molecules. They promote interactions between cells and their environment, being both other cells or the extra- cellular matrix. Integrins are a family of heterodimeric membrane glycoproteins consisting of non-covalently associated subunits, i.e. an α-subunit of 95 kDa that is conserved through the superfamily and a more variable β subunit of 150-170 kDa. More than 18 α and 8 β subunits with numerous splice variant isoforms have been identified in mammals. The integrin α5 chain (160 kDa) (CD49e), undergoes post-translational cleavage in the extracellular domain to yield disulfide-linked light (25 kDa) and heavy (135 kDa) chains, which non-covalently associate with the integrin β1 subunit (CD29) (130 kDa), thus forming the heterodimer α5-β1 very late antigen (VLA-5) complex. VLA-5 is a fibronectin receptor (FNr) that is expressed on thymocytes, T-cells, monocytes and platelets. It is also found on very early B-cells and activated B-cells. VLA-5 mediates binding of T- and B-cells to fibronectin, an extracellular matrix glycoprotein involved in cell adhesion and migRation in wound healing, embryonic development and malignant transformation. The VLA-5 or FNr binds only fibronectin recognizing the Arg-Gly-Asp (RGD) sequence in the central region of the molecule.

Antibody s specificity
NKI-SAM-1 recognizes the 135-kDa integrin- alpha 5 monocyte-specific antigen. As a result NKI-SAM-1 strongly reacts with monocytes, and weakly with granulocytes, platelets and T-lymphocytes. Its exact epitope is not known.

Antibody s suited for
NKI-SAM-1 is suitable for flow cytometry (recommended range is 1:200 – 1:500, using 0.2-0.5 µg for 10^6 cells) and can be used to determine the VLA-5 expression in peripheral blood monocytes and monocyte derived dendritic cells (see refs 2 and 3), B cells and B-cell precursors (ref. 4), and in the less pathogenic yeast Candida species (ref. 5). NKI-SAM-1 can also be applied in immunohisto-chemistry on frozen tissues, immunocytochemistry and immunoprecipitation. Optimal antibody dilution should be determined by titration.

Description
The Mouse anti Integrin alpha 5 (CD49e) is a α- or alpha protein sometimes glycoprotein present in blood. This 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.
-
Test
Mouse 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.
