Integrin subunit aL/CD11a is a 180kD type I TM glycoprotein that interacts only with Integrin b2/CD18 to form LFA-1, a leukocyte adhesion protein which binds endothelial cell ICAM. Human Integrin aL (Accession # P20701) contains a 1064 amino acid (aa) extracellular domain (ECD), a 20 aa TM sequence and a 58 aa cytoplasmic domain. The ECD contains seven repeats that form a beta-propeller structure and one inserted vWA domain (I domain) containing a metal ion-dependent adhesion site (MIDAS). Human and mouse Integrin aL ECD share 74% aa identity. A second isoform has a 53 aa insertion in the ECD.
Suitable for use in Flow Cytometry. Other applications not tested.
Flow Cytometry: Use 10ul to label 10e6 cells.
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 and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20 degrees C. Aliquots are stable for at least 6 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.
