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 and the extra cellular matrix. Integrins are a family of heterodimeric membrane glycoproteins consisting of non-covalently associated subunits, being 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. One of the integrin alpha subunits is the integrin alpha 6 (α6) subunit. Integrin α6 (CD49f) primarily associates with the integrin beta 1 (β1) or beta 4 (β4) subunit to form the α6β1 or laminin receptor and the α6β4 heterodimer. The GoH3 monoclonal antibody recognizes cell surface antigens on epithelial cells, endothelial cells and in a variety of tissues in both Human and Mouse, and reacts with glycoproteins Ic (α6 integrin, also known as CD49f) complexed with glycoprotein IIa (β1) as the VLA-6 (very late activation antigen) or laminin receptor on Human and Mouse platelets, lymphocytes, epithelial cells and a variety of other cell types. In normal epithelial cells and (colon) carcinoma cells, peripheral nerves, and endothelia however, glycoprotein Ic (α6) is not associated with IIa, but with a group of proteins collectively named β4. These β4 proteins can occur in multiple forms on certain cell types. The tumor associated homologue of this protein is the TSP-180 antigen, expressed in lung carcinomas, melanomas, Human tissue carcinomas and carcinoma cell lines but not on Human melanomas and fibroblasts. VLA-6 is expressed on peripheral T cells or thymocytes, the GoH3 monoclonal antibody induces a comitogenic signal and inhibits platelet adhesion to laminin, one of the three major components of the subendothelial matrix.

Antibody s specificity
The epitope recognized by GoH3 is loCated on glycoprotein Ic or the a6 subunit of integrin. This α6 (glycoprotein Ic) is expressed as a physical complex with glycoprotein IIa within the plasma membrane protein on platelets and with the b4 subunit of integrin on normal epithelial cells and (colon) carcinoma cells, peripheral nerves, and endohelia. The epitope of the monoclonal antibody is still available when the Ic glycoprotein is within the complex.

Antibody s suited for
GoH3 can be used in flow cytometry, immunoprecipitation and immunocytochemistry. Optimal antibody dilution should be determined by titration. In immunohistochemistry staining of frozen Human tissues. GoH3 stains the basement membrane zone in skin sections, the myoepithelial cells in the mammary gland, tubules in kidney sections, acini and ducts in salivary glands, the epithelial layer in colonic crypts, the perineurium and the Schwann cells in sections of Human peripheral nerves. Smooth muscle cells, endothelial cells and striated muscle and the muscularis of the large intestine are not stained.

Description
The anti Integrin alpha 6A / CD49f 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.

About
Rats are used to make rat monoclonal anti mouse antibodies. There are less rat- than mouse clones however. Rats genes from rodents of the genus Rattus norvegicus are often studied in vivo as a model of human genes in Sprague-Dawley or Wistar rats.
