Guinea pig complement
Pooled guinea pig serum is rapidly collected and frozen-preserving complement activity-and lyophilized. It is specially collected and processed under "Cold Room" conditions which maintains maximum complement activity. Guinea pig serum characterized for both classical and alternative pathway activity. Guinea pig serum complement is suitable for in vitro experiments relating to complement activation. It has been widely used in biomaterials research and pharmaceutical development. It is ideal for experiments and assays for which a high level of in vitro complement activity is necessary or a low level of complement activation fragments is required.
Whole sheep serum, 2 mL
Product is whole sheep serum and buffer salts. This product is suitable for use as a serum protein control in immunoelectrophoresis, Ouchterlony immunodiffusion, and other immunoprecipitation techniques. It may also be used as a blocking agent in fluorescence and enzyme immunoassays.
Washed, preserved sheep red blood cells (10%) suspension), 20 mL
Product is 20 ml of a 10% suspension of sheep red blood cells collected into Alsever's solution (Dextrose, sodium chloride, sodium citrate), washed with phosphate buffered saline and preserved with borate buffer, sodium acetate and 1% penicillin streptomycin.
Whole rabbit serum, 2 mL
Product is whole rabbit serum and buffer salts. Whole serum is suitable for use as a serum protein control in immunoelectrophoresis, Ouchterlony immunodiffusion, and other immunoprecipitation techniques. It may also be used as a blocking agent in fluorescence and enzyme immunoassays.
Rabbit complement type (Hla-Dr), 5 mL
The complement is produced from a large pool of New Zealand White rabbits, 8-12 weeks old. The animals are of United States origin. Cytotoxic titer is determined by NIH standards for microlymphocytotoxicity. Minimum release criteria is 80%-100% cell death in 1:2 dilution.
Mouse immunoglobulin reference serum, 1 mL
This product is pooled from outbred adult male and female ICR/Swiss Webster mice. The immunoglobulin levels, except IgE, are determined by radial immunodiffusion. The IgE level is obtained by addition of monoclonal IgE (Anti-DNP, Code No. 630122).
See Rat and Mouse Immunoglobulin Reference Sera in the Immunobiologicals section for immunoglobulin values.
