Leukocyte surface antigen p150,95 (ITAX) shares a beta subunit with 2 other members of the leukocyte adhesion molecule family, Mac-1 and LFA-1, but has a unique alpha chain. The extracellular domain contains three tandem homologous repeats of approximately 60 amino acids with putative divalent cation-binding sites, and four weaker repeats which lack such binding sites. The ITAX alpha subunit is homologous to the alpha subunits of receptors which recognize the RGD sequence in extracellular matrix components, as has previously been shown for the beta subunits, supporting the concept that receptors involved in both cell-cell and cell-matrix interactions belong to a single gene superfamily termed the integrins. Distinctive features of the ITAX alpha subunit include an insertion of 126 residues N-terminal to the putative metal binding region and a deletion of the region in which the matrix receptors are proteolytically cleaved during processing (1). The alpha subunit of the leukocyte integrin p150,95 (CD11c) is a transmembrane polypeptide of 1144 residues whose long extracellular region contains three putative divalent cation binding repeats and a 200- amino acid inserted or "I" domain.
Applications:
Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested.
Recommended Dilution:
Immunohistochemistry: paraffin sections.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
