Weitere Details:: CD55 (Decay-accelarating factor/DAF) is a glycoprotein member of the RCA family of molecules. It is found on blood cells, epithelium and endothelium and serves both as a receptor for CD97 and a negative regulator of the C3 convertases, C4b2a and C3bBb. Mature mouse CD55 is the product of two genes that arose by duplication. There is a 55-60kD, 356 amino acid (aa), GPI-linked form that is ubiquitously expressed. This molecule contains four SUSHI domains (aa 35-285), a Ser/Thr-rich region (aa 288-362) and a GPI-anchor at Gly362. There is also a 50kD, 379 aa, type I transmembrane form that is testis-associated. It shows the same domain architecture and is 93% aa identical to the GPI-form. At least four GPI gene isoforms exist. They diverge after Ile285 and show deletions and substitutions. Over aa 35-359, mouse CD55 is 66% and 50% aa identical to rat and human CD55, respectively. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 0.1-0.2ug/ml with the appropriate secondary reagents to detect mouse CD55. The detection limit for rmCD55 is approximately 1ng/lane and 5ng/lane under non-reducing and reducing conditions, respectively. Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute by adding sterile 40-50% glycerol, aliquot and store at -20°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.
