Extra Details:: The LW glycoprotein has recently been renamed ICAM-4 due to its similarity to intercellular adhesion molecule, although exactly which integrins bind to ICAM-4 is subject to controversy. The function of ICAM-4 is not fully understood but appears to be restricted to erythroid cells. During in vitro erythropoesis, LW appears at either the erythroid colony forming stage or later at the proerythroblast stage. A vital part of erythropoesis is the clustering of erythroblasts around bone marrow macrophages to form erythroblastic islands. The erythroblast is then able to remove its nucleus, which is in turn ingested and broken down by the macrophages, to become a mature erythrocyte. During this process ICAM-4 binds to VLA-4, an erythroblast binding site, on adjacent erythroblasts and to alphav integrins on macrophages to help stabilise the erythroblastic islands. Applications: Suitable for use in ELISA, Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested. Recommended Dilution: Western Blot: 1:50-400 Immunocytochemistry: 1:50-500 Immunohistochemistry (frozen): 1:50-500 Immunohistochemistry (paraffin): 1:10-100 ELISA: 1:100-1:5000 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt.
