Affinity purification of human factor H on polypeptides derived from streptococcal m protein: enrichment of the Y402 variant.
Recent studies indicate that defective activity of complement factor H (FH) is associated Undercounter Dishwashers with several human diseases, suggesting that pure FH may be used for therapy.Here, we describe a simple method to isolate human FH, based on the specific interaction between FH and the hypervariable region (HVR) of certain Streptococcu
