Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
NCTC clone 2472 was derived in May, 1956, by K.K. Sanford, et al. from NCTC strain 1742 (Subline VII) of the parent NCTC clone 1328.
The parent line was derived by G.D. Likely et al. in November, 1950, from a culture of subcutaneous areolar and adipose connective tissue taken from a normal 82-day-old male C3H/HeN mouse.
While cultures of NCTC strain 1742 produced sarcomas in 97% of the mice injected, cultures of NCTC clone 2472 under similar conditions produced sarcomas in 65% of the mice injected.
NCTC clone 2472 has been compared with related clones, such as NCTC clone 2555 (ATCC CCL-12), and certain other cell lines with respect to neoplastic and physiologic properties, nutitional needs, karyology, enzyme activities, and rates of glycolysis.
NCTC clone 2472 cells have been cultured since origin in an antibiotic-free mixture of medium NCTC 109 (135) with 10% horse serum.
Plating efficiency is approximately 10% in the recommended culture medium.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:5 is recommended
Medium Renewal: 3 times per week
