Fig. S. Inhibition of the binding or rabbit anti-HCG to human chorionic gonadotropin (HCG) beads by differing amounts of HCG as measured by inhibition of [ I]PA binding. (A) Effect of varying antibody concentration on assay sensitivity. Inhibition curves were obtained using 13 ig of HCG beads and anti-HCG diluted li ( — 14,2(X) cpm bound), jhi (O—O 80(X) cpm bound), orj W (A—A 4250 cpm bound). (B) Effect of varying bead concentration on assay sensitivity. Inhibition curves obtained using anti-HCG diluted jin and either 40 ng (O—O 23,500 cpm bound), 13 /xg ( — 14,200 cpm bound), or 4.3 fig (A—A 6000 cpm bound) of HCG beads. In each case, 38,000 cpm of [ I]PA were added. From Langone. ...

This action of catechic tannins is due to their high absorption capacity for ultraviolet light, especially that absorbed by riboflavin at 370 nm, which prevents it from reacting with methionine. This explains why red wines, with their high procyanidin content, are much less light-sensitive. Inhibition of the amino acid photolysis reaction may also be explained by the fact that phenols are scavengers of free radicals. 

The presence of ATP leads to a weakening of FNR-thyledtoid interactions and modifications in PSI-dependent electron transfer reactions to NADP. The light-stimulated phosphorylation leads to an antimycin a sensitive inhibition of light saturated NADP photoreduction. 

DBS ARM binding was sensitively inhibited by free prpgesterone-lla-hemi-sucdnate (IC50 3 X 10" M). When the series of progesterone derivatives was used, the order of reactivity (above) was the same as that with the native anti-... 

Numerous bacteriocins are produced by lactic acid bacteria (Klaenhammer, 1988), but only a few bacteriocins have been found in propionibacteria (Lyon and Glatz, 1991, 1993 Giinstead and Barefoot, 1992). Recently, 14 dairy propionibacteria were screened for catalase-insentitive, protease-sensitive inhibition of Gram-positive and Gramnegative bacteria (Ratnam et al., 1998). Bacteriocin production was identified in 57% of these cultures. 

System A activity was first described for the Ehrlich ascites tumor cell in 1963 in the now classic investigation by Oxender and Christensen (15). The activity was Na" -dependent, pH-sensitive, inhibited by high concentrations of intracellular amino acids, and showed a preference for neutral amino acids with small or unbranched sidechains. A large body of literature published over the last 2 decades has delineated several other...
