Featured Products
- IgG/IgM Depleted Human Complement Single Donor – Suitable for functional antibody assays (SBA-Serum Bactericidal Assay, MOPA/OPA- Multiplexed /Opsonophagocytic Killing Assay) for vaccine evaluation. Complement components are extremely heat-sensitive; for best results, thaw complement on ice or in a cold water bath. Aliquots may be made and frozen at -70°C or below. Avoid multiple freeze-thaw cycles. When a working aliquot is thawed, do not re-freeze remaining complement, but discard it.
- Rabbit Serum Sterile Non-Hemolyzed Delipidized Young – Reportedly useful in immunohistochemistry assays and western blot; as diluent, blocking agent, cell culture/ growth supplement and source of serum proteins.
- Guinea Pig Complement – Reportedly useful in complement-dependent cytotoxicity assays and immunoprecipitation techniques.
- Bovine Cardiac Acetone Powder – Useful for protein purification such as actin, myosin, and troponin.
