[MOPC 21]
Ascites fluid, collected from Balb/c mice which carry plasmacytomas subcutaneously, are clarified by centrifugation and filtration. It is dialyzed, adjusted to yield at least 5 mg of immunoglobulin, then vialed and lyophilized. Clarified ascites are tested for immunoglobulin by immunoelectrophoresis using antisera specific for the particular type and isotype. Approximately 10% of the total protein is immunoglobulin (including trace levels of the host's immunoglobulins), 80% is albumin, and 10% is complement and other proteins.

Proteinase K is a highly active stable endopeptidase with a broad spectrum of action was isolated by E. Merk's Darmstadt Biochemical Research Department in 1970 from a culture filtrate of the fungus, Tritirachium album Limber. This fungus is able to grow on Keratin (e.g., wool, horn particles) as the sole source of carbon and nitrogen. The isolated protease was, therefore, given the K designation.

Isopropyl b-D-1-thiogalactopyranoside is a non-metabolizable galactose analog that induces expression of the lac operon in Escherichia coli. It functions by binding to the lac repressor and altering its conformation. This inactivation prevents the repression of the b-galactosidase coding lac gene.

HEPES is a zwitterionic organic chemical buffering agent; one of the twelve Good's buffers. HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by cellular respiration) when compared to bicarbonate buffers, which are also commonly used in cell culture. Its dissociation decreases as the temperature decreases which makes it a more effective buffering agent for maintaining enzyme structure and function at low temperatures.

The complement system provides innate defense against microbial infection and is a "complement" to antibody mediated immunity. The complement system consists of thirty-five interacting plasma and membrane associated proteins which contribute to host-defense and initiate and amplify inflammation, even in the preimmune state where specific antibodies and lymphocytes are not available. In addition to the complement components themselves, this system also contains several soluble factors that prevent spontaneous complement activation from occurring in solution, as well as, several regulatory membrane associated proteins that protect host cells from accidental complement attack. Cleavage of the C3 component by either the classical pathway or the alternative pathway releases C3a and C3b. C3a appears to be important in many inflammatory responses while the C3b fragment covalently binds to the cell or bacterial surface and plays a role in opsonisation. Binding of C3b to the C4b component of the C3 convertase, results in C5 convertase (C4b3b2a) formation.

The total protein is measured using the Biuret procedure with bovine albumin as the standard. To ensure that the product titer falls within the required range, antibody titer is standardized by microtiter plate ELISA with mouse complement C3. The product is tested for purity and specificity at final concentration by immunoelectrophoresis. The antibody is predominantly goat IgG; no trace of albumin is detected.
