Abstract: An agglutination immunoassay for antibody wherein antigen for sensitizing a solid particulate support is treated with detergent. The resultant antigen-sensitized support is resistant to self-agglutination.

Abstract: Peptide fragments of streptococcal M protein named CB3, CB4, and CB5 and related synthetic peptides have been identified. When linked to a protein carrier which is polylysine the conjugates of CB3, CB4, CB5, and S-CB3 are capable of evoking type specific opsonic antibodies against streptococci.

Abstract: This invention is directed to AUT-PK 500, a novel autophosphorylating protein kinase, to the purification and characterization of AUT-PK 500 from rat adrenocortical carcinoma, to the use of AUT-PK 500 as a marker for neoplasia cells, and to a radioimmunoassay for detecting AUT-PK 500 in neoplasia cells.

Abstract: A method is provided for treating psoriasis and seborrheic dermatitis in humans by topical application of an effective, lesion reducing amount of an imidazole antibiotic to affected areas.

Abstract: Methods and apparatus for on-line detection and measurement of degradation or undesirable changes in the time constants of sensors used in monitoring a system are disclosed. Methods and apparatus of this invention are particularly suitable for use in complex and high-risk industrial processes or other operations where it is undesirable and expensive or dangerous to allow certain parameters of the operation to change above or beyond a predetermined amount. This invention includes a detector for determining when a signal from a sensor crosses a preselected signal level such as for example a zero level. The output of the detector or zero crossing detector is provided to a counter or other means which determines the rate of the zero crossing by counting the number of crossings per a specific time period provided by a timer.
