MCQ (Single Correct) +4 −1

Which of the following is a Fish Cell Line ?

RTG-2 Correct Vero HeLa BHK21

RTG-2 Fish Cell Line:
RTG-2 (Rainbow Trout Gonad-2): The first continuous, permanent cell line established from a poikilothermic aquatic animal, derived from the gonads of juvenile rainbow trout (Oncorhynchus mykiss) by Ken Wolf and M.C. Quimby in 1962.
RTG-2 is universally used in aquatic virology to isolate and culture fish viruses (e.g., IPNV, VHSV).
HeLa, Vero, and BHK21 are mammalian cell lines.
Correct Option: Option 1 (RTG-2).
