· Neural Stem Cell Basal Medium (Part No. SCM003) should be stored at -20°C until ready to use. Upon thawing, the basal medium should be stored at 2-8°C for up to one month.
· Basic FGF (10 µg, lyophilized) should be reconstituted with 100 µL 5 mM Tris-HCL, pH 7.6 for a final concentration of 100 µg/mL. Dispense into aliquots to avoid repeated freeze-thaw. Store at -20°C for up to six months. This solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or -20°C for future use. Multiple freeze/thaw cycles will result in significant loss of activity.
· 5 mg/mL Puromycin Solution, 100 µL (Part No. CS201361) should be stored in working aliquots at -20°C for up to two years.
