test drop downs for 7.1 reagents

**10 mM ATP stock** (from Maniotis) 60 mg ATP in 8 mL H2O pH to 7.0 with 0.1 M NaOH Bring volume to 10 mL with H2O Aliquot and freeze. ------------------------------ **10 µM solution for use (=5.731 mg/L) in HBS** Make enough for Labs 7.1 and 7.2:
Lab 7.1: 0.750 mL per coverslip x 4 coverslips x 7 groups = 21 mL
Lab 7.2: 0.75 mL per coverslip x 2 coverslips x 7 groups = 10.5 mL Make 40 mL
40 µL 10 mM ATP stock in 40 mL HBS (1 µL 10 mM ATP stock per 1 mL HBS.) Make 24 aliquots of 1.6 mL (16 for Lab 7.1, 8 for Lab 7.2

Make 24 aliquots of 1.6 mL (16 for Lab 7.1, 8 for Lab 7.2
