KB-celler utgör en sidolinje till den utbredda, keratinbildande tumörcellinjen HeLa. KB-linjen troddes ursprungligen härröra från ett epidermiskarcinom i munhålan, men befanns så småningom, mha isoenzymanalys, HeLa-markörkromosomer och DNA-fingeravtryck, ha uppkommit genom kontaminering med HeLa-celler. Cellerna är keratinpositiva vid immunperoxidasfärgning. KB-celler har rapporterats innehålla sekvenser av humant papillomvirus 18 (HPV-18).
This line KB is now known to be a subline of the ubiquitous KERATIN-forming tumor cell line HeLa. It was originally thought to be derived from an epidermal carcinoma of the mouth, but was subsequently found, based on isoenzyme analysis, HeLa marker chromosomes, and DNA fingerprinting, to have been established via contamination by HELA CELLS. The cells are positive for keratin by immunoperoxidase staining. KB cells have been reported to contain human papillomavirus18 (HPV-18) sequences.
