Results: The commonly used sheep erythrocyte sensitized with rabbit antibodies were not sensitive to lysis by goat serum, but the combination of human red blood cells (RBC) plus rabbit antibodies was the best option found for goat complement assay. A buffer based on HEPES instead of the classical veronal (barbitone) was developed. Three proteins were isolated: factor H, C1q and C3 and these were compared with the corresponding human proteins. A novel affinity chromatography technique was developed for isolation of factor H. Conclusions: Human RBC plus rabbit antibodies were a suitable option for haemolytic assays. The isolated proteins are similar to the human counterparts.||URI:||http://hdl.handle.net/10553/7889||ISSN:||1746-6148||Other Identifiers:||http://dx.doi.org/10.1186/1746-6148-8-91||DOI:||10.1186/1746-6148-8-91||Source:||Bmc Veterinary Research[ISSN 1746-6148],v. 8|
