Serum free supernatant of vector transfected CHO cells
(Control supernatant for Cat No 011-3a)



CHO-cells, transfected by expression vector p-POL- DHFR lyophilized,
for reconstitution add 100 µl water



CHO-S-SFM-II(Gibco) + antibiotics, without NaN3

Special note

The transfected CHO cells were cultivated in a mini-reactor (same procedure like Cat 011-3a) and the supernatant than harvested in the same manner as CD14 transfected CHO cells


100 µg


long time storage at -80°C


Product is unpurified cell culture supernatant.
