Our rabbit serum is collected from donor, pathogen-free animals. All serums are 0.2uM filtered and test negative for microbial growth. Rabbit serum contains high amounts of macromolecules, nutrients, enzymes, and hormones that promote healthy cell growth. Rabbit serum can be used as a supplement instead of FBS in various cell culture models as well as a blocking buffer for immuno-assays. Heat-inactivated serum can be made upon request.
