Abstract: Hybridoma tumor cell line A.T.C.C. No. HB8116. An anti-H-Y antigen monoclonal antibody substance, "Hyclonalan," produced by said cell line. Use of Hyclonalan in immunoselection methodology.
Abstract: A method of determining (1) the activity of complement, (2) the bacteriolytic activity of serum, or (3) the titer of antibody in a sample which comprises: (a) incubating complement-sensitive microorganisms containing an assayable intracellular component with the sample, and (b) detecting the assayable component released into the sample by lysis of the microorganisms.
Abstract: An HLA-DR typing test based on lymphocytotoxicity in which a vital dye-labeled total human lymphocyte sample, such as a sample of peripheral blood lymphocytes, is incubated with HLA-DR antisera, a monoclonal antibody against T cells, and complement and the DR type is determined based upon the resultant cytotoxicity as measured by the fluorescence of B cells surviving the incubation.

Abstract: Method for detecting circulating immune complexes containing endogenously bound Clq. Capillary tubes are filled with a mixture of Clq coated GPO reagent cells, rabbit anti-Clq antibodies, and precipitate from the biological fluid sample containing immune complexes. The mixture is allowed to react and the tubes read for the presence or absence of agglutination indicative of the absence or presence of said immune complexes respectively.
Abstract: A particle counting assay for haptens (small non-protein monovalent substances having a molecular weight below 1500) comprises mixing a liquid sample (e.g. of human origin) containing the hapten, with finely divided inert particles bearing the same hapten (or a specific analogue thereof), an agglutinator such as RF or C1q, and a measured amount of antibody, which amount is insufficient to cause agglutination of all the particles. The amount of hapten is determinable by measuring the extent of the agglutination.
