Ionomycin

Raises intracellular calcium levels

Fisher or Invitrogen (Life Technologies) I24222

1 mM in DMSO or EtOH. 1 mg makes 1.34 mL stock.

3 µM Ionomycin in HBS
Dilute stock 1:333 in HBS: 3 µL/1 mL

24 µL in 8 mL, aliquot 800 µL

They only need 750µL, because they do one experiment in HBS, then two in Ca-free HBS.

3 µM Ionomycin in Ca-free HBS
Dilute stock 1:333 in Ca-free HBS: 3 µL/1 mL
45 µL in 15 mL

Takes a long time to thaw. Vortex.

Aliquot 1.55 mL so they can do two 750 µL experiments
