ADAMTS13 (A disintegrin and metalloprotease with TSP motifs 13) is a 140-230kD, secreted glycoprotein member of the ADAMTS family of proteases. ADAMTS13 is produced by the liver and circulates in plasma where it cleaves and reduces the activity of von Willebrand factor. ProADAMTS13 is 1398aa in length. It contains a 45aa prodomain (aa30-74), one peptidase domain (aa80-286) and one disintegrin (aa287-383) domain, multiple TSP regions and two CUB domains. The prodomain does not affect activity, while the TSP and CUB domains appear to be necessary for activity. One truncated form exists that shows truncation after Gln448. Over
aa34-688, human ADAMST13 shares 76% aa identity with mouse ADAMST13.
Applications:
Suitable for use in ELISA, Western Blot, and Immunoprecipitation. Other applications not tested.
Recommended Dilution:
ELISA: 0.5-1.0ug/ml
Western Blot: 0.1-0.2ug/ml
Optimal dilutions to be determined by the researcher.
Storage and Stability:
Lyophilized powder may be stored at 4 degrees C for short-term only. Reconstitute to nominal volume by adding sterile 40-50% glycerol and store at -20 degrees C. Reconstituted product is stable for 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.
