Reagents for 6.3

HBS-BSA 1mg/mL

  • to mix transferrin ( 3 mL) and nocodazole (15 mL) in

  • to rinse growth medium off before and after treatment. 6 mL per dish x 3 dishes per group x 7 groups = 126mL. Aliquot 20 mL.

  • make 200 mL

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
