Transferrin in Fe-HBS-BSA
Alexa-Fluor 488 transferrin (Invitrogen T13342, MW = ~80KD)
stock is 5 mg/mL (=62.5 µM).
Final concentration = 1 µM.
- Each group may do up to 3 100 µL treatments (= 3 x 7 x 105 µL = 2.205 mL)
- Make 105 µL aliquots (21)
- Make 2.3 mL: 36.8 µL AF-488-Tf + 2.263 mL Fe-HBS-BSA
if new transferrin stock is needed add 1 mL sterile distilled water to the new bottle.

Nocodazole
Acros 358240100, 10 mg
1µM in HBS-BSA
(Working concentration range is usually 100nM - 30 µM.)
Stock is 10 mg/mL (=33mM)
(Add 1mL DMSO to 10 mg in bottle = 33mM. Aliquot 3.03 µL. To make 1mM, add 97 µL.)
Make enough for each group to do two 1 mL treatments.
Aliquot 1.01 mL per tube, 15 tubes = 15 mL. Make 16 mL
- Add 97 µL HBS-BSA to 3 µL 33mM in tube to make 1 mM
- Mix 1 part 1mM with 999 parts HBS-BSA to make 1µM: 16 mL + 1.6 µL
