Work Serum-Free with PBMC! 

Up until now, freezing and testing of PBMC has required the use of serum. Serum contains a plethora of bioactive molecules whose variable concentrations render each batch unique. Each lot must therefore be tested, which makes working with serum both expensive and time-consuming.

CTL scientists have formulated a revolutionary new media portfolio that permits each step of the ex vivo PBMC work to be performed without serum. When frozen in accordance with CTL protocols, PBMC maintain their full functionality in ELISPOT assays. more...
