Introduction of a new Rapid Microbial Method (RMM) requires a full validation. The purpose of the validation is to prove that equivalent or better results are obtained using the new method when compared to the compendia. One assumes that the result obtained with the compendial method is absolute and is the “Gold Standard†by which to compare the new test. In reality, the compendial method exhibits a number of weaknesses that compromise the integrity of the validation. The standard requires…
Transient transfection in mammalian cell lines provides an avenue for researchers to bridge the development bottleneck and shorten the time to usable protein. The method also maintains post translational modifications crucial for biotherapeutic function. Chinese Hamster Ovary (CHO) suspension cells are especially suited for high yield production of recombinant proteins, despite being refractory to commonly used transfection methods (e.g. 25kDa linear PEI). Mirus Bio has developed a more effective alternative, the TransIT-PRO® Transfection Kit. Transfection efficiencies are affected by many…
