Using :

Thaw at 4˚C overnight or in a 37˚C water bath. After thawing, we recommend you aliquot and store at -80˚C. This READY-to USE formulation does not require the addition of Heparin to the final medium concentration. This formulation is designed to be used at the same ratio as traditional Fetal Bovine Serum (FBS).

Particulate Formation :

Upon thawing, the product may be visually cloudy or have floating debris, similar to FBS. It is most optimal to reduce this possibility by minimizing multiple freeze/thaws, letting stem serum replacement warm in the 37oC water bath for an extended period of time, or extended storage at 4°C.
Some particulate formation can be reversed with a brief incubation at 37°C. Filtration is not necessary and Stem Serum Replacement performance is not reduced by the appearance of particulates.


Stem Serum Replacement is derived from bovine proteins. SSR contain bovine growth factors including; Albumin, Glucose, Globulin, Cholesterol, Urea, EGF, VEGF, TGF-beta1, Calcium and other proteins. The replacement is then 0.2um sterile filtered. The product is shipped frozen on dry ice. Store at -20°C or greater. (-80°C is preferred for long-term storage)
