cobalt chloride not inducing hypoxia
Posted 28 July 2012 - 08:32 PM
I am trying a Hypoxia induction on PC 12 cells by using CoCl2 i have read certain papers n concluded that 150-200uM conc. is enough for 40-50% cell death..But when i m trying this in my lab there is no Hypoxia even at 300uM conc....
earlier i thought there is some problem in my calculations or my stock so i prepared the stock again but still the result is same.. what do i do???plz help anyone???its kind of frustrating....
i am giving a 24hrs incubation n cells are maintained in 5% serum and evaluation is done by MTT assay(we do cell synchronization also)...
plz help ..anyone...

I found a paper using cobalt on PC 12 and their viability chart have 50 % cell death in concentrations around 600 uM of CoCl2.
It's not freely accessible so I send it to you as a PM.

Cobalt chloride induces PC12 cells apoptosis through reactive oxygen species and accompanied by AP-1 activation.

I never trust anything that can't be doubted.
