Chemical and Physiological Properties of an Antibiotic Produced by a Variant of the Penicillium Notatum-Chrysogenum Group

Chemical and Physiological Properties of an Antibiotic Produced by a Variant of the Penicillium Notatum-Chrysogenum Group

Date: 1947
Creator: Conyers, Loyd, W.
Description: The present study of the production and properties of an antibiotic was undertaken in the hope that some useful information could be contributed to a long-range investigation program being carried on at North Texas State Teachers College. This program is concerned with the production of a useful antibiotic from a variant of the Penicillium notatum-chysogenum group of molds.

The Effect of Repeated Antigen Injections on the C' and C'4 Titers in Guinea Pig Serum

The Effect of Repeated Antigen Injections on the C' and C'4 Titers in Guinea Pig Serum

Date: June 1961
Creator: Teague, Perry Owen
Description: In this study the effects of repeated antigen injections on total complement (C') and C'4 of guinea pig serum were investigated to determine if constant antigenic stimulation would show changes in the C' and C'4 titers. Attempts were also made to correlate any changes with variations in antibody titers during the repeated antigen injections.
