Dimethyl sulfoxide (DMSO) is used as a cryopreservant for mammalian cell cultures because GATE-Biotechnology1 AnswerSince mammalian cells are sensitive to shear, scale-up of a mammalian cell process must consider, among other parameters, the following (given N = rotations/time, D=diameter of impeller). -Gate Biotechnology 2014 question paper1 AnswerThe growth medium for mammalian cells contains serum. One of the major functions of serum is to stimulate cell growth and attachment. However, it must be filter sterilized to: (-Gate Biotechnology 2014 question paper)1 AnswerDetermine the correctness or otherwise of the following Assertion (a) and Reason (r). GATE-Biotechnology1 AnswerIn a mouse genome, the numbers of functional Vα, Jα, Dβ, Jβ gene segments are 79, 38, 21, 2 and 11, respectively. The total number of possible combination for αβ T cell receptors are ______ x106 . (-Gate Biotechnology 2014 question paper)1 AnswerIn an exponentially growing batch culture of Saccharomyces cerevisiae, the cell density is 20 gl^-1 (DCW), the specific growth rate is 0.4^1 and substrate uptake rate (v) is 16 gl^-1h^-1.
