The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Bioactivity: Measured by binding ability in a functional ELISA. When ab168708 is coated at 1 µg/mL (100 µL/well), the concentration of recombinant Human CD97 that produces 50% of the optimal binding response is found to be approximately 0.15-2.0 µg/mL.
< 1.000 Eu/µg

Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
pH: 7.40 Constituent: PBS Note: 5-10% trehalose is commonly used for freeze drying, and after reconstitution, the trehalose is mostly about 3-5%
This product is an active protein and may elicit a biological response in vivo, handle with caution.
It is recommended to reconstitute the lyophilized protein in sterile deionized water or buffer. Please refer to the batch CoA for more details. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade.
Expressed on the plasma membranes of all cell types that are in intimate contact with plasma complement proteins. It is also found on the surfaces of epithelial cells lining extracellular compartments, and variants of the molecule are present in body fluids and in extracellular matrix.
Belongs to the receptors of complement activation (RCA) family. Contains 4 Sushi (CCP/SCR) domains.
The first Sushi domain (SCR1) is not necessary for function. SCR2 and SCR4 provide the proper conformation for the active site on SCR3.
The Ser/Thr-rich domain is heavily O-glycosylated.
