Vasopressin

1 mg/mL (= 0.9225 mM) Vasopressin stock in water

---

1 µM dilution to make student solutions

1 µL 1 mg/mL in 922.5 µL water (NO CALCIUM, so stock can be used for Ca-free solutions )

---

10 nM (= 1.084 µg/mL) Vasopressin in HBS for students

Use Vasopressin aliquots from Lab 7.1

Calcium Free Vasopressin 10 nM

10 nM (= 1.084 µg/mL) for students

1 part 1µM dilution to 99 parts Ca-free HBS

Lab 7.2: 0.75 mL per coverslip x 2 coverslips x 7 groups = 10.5 mL

Make 13 mL: 130 µL + 13 mL Ca-free HBS

Make 8 aliquots of 1.6 mL
