pulse-chase analysis An experiment in which a radioactively labeled precursor compound is added to cells or a cell extract in vitro for a short period (pulse), after which a large excess of unlabeled compound is added to dilute and prevent further significant incorporation of radioactivity. Samples are taken at various times to follow the course of the radioactive precursor as it is metabolized (chase period).

Puma lentivirus (PLV-14) (PLV) A species in the genus Lentivirus. Infectious puma lentivirus has been isolated from several Florida panthers. The virus can be grown in a domestic cat lymphoma cell line 3201. Genomic DNA from a Florida puma, Felis concolor coryi, infected with the PLV 14 strain of PLV was sequenced and found to be closely related to Feline immunodeficiency virus.
