purified protein derivative (PPD). [pyoÌoÌâ²rifÄ«d]. a dried form of tuberculin used in testing for past or present infection with tubercle bacilli. This product is usually introduced into the skin during such tests and may produce a tuberculin reaction (wheal) within 48 to 72 hours.
CD30. The CD 30 gene is located at on chromosome one at 1p36. It appears to be a lymphoid activation gene and is part of the nerve growth factor/TNF superfamily. The protein product is a 120 kDa transmembrane glycoprotein 8. Its ligand, CD30L, has homology to TNF.Ber-H2 identifies an epitope which survives routine fixation and processing 9.he Ki-1 antibody recognises both an intracellular protein and a transmembrane glycoprotein, which are apparently unrelated. Reaction with the former may account for some positivity with Ki-1 which cannot be reproduced using Ber-H2. The transmembrane glycoprotein is often referred to as the true CD 30 antigen.
