Possible Interaction: Gelatin and Purified Protein Derivative Of Tuberculin

“… gelatin , though eliciting firmer and larger reactions than … the latter, either in the human PPD used to detect specific tuberculin sensitivity or in the avian PPD used to detect non-specific tuberculin … reactions to a greater extent in persons with low-grade sensitivity than in those with strong sensitivity.”

“ Gelation of F-actin can be induced by the addition of the purified protein , and this can be inhibited by Ca2+ (half maximal inhibition, 2 microM).”
