Description

  • Prepare 3 sets of hydrogels with phosphate buffers

A)0.51 g of PVOH (MW:89,000-98,000) with 4 ml of phosphate buffer was placed on to a heat block at 100C.

B)0.25 g of PVOH (MW:89,000-98,000) with 3 ml of phosphate buffer was placed on to a heat block at 100C.

C)0.14 g of PVOH (MW:89,000-98,000) with 3 ml of phosphate buffer was placed on to a heat block at 100C.

  • Add 2μ of R6G were added for each ml of phophate buffer. Add 6μ R6G in to B and C. Add 8μ to A.
  • Homoginize each of the hydrogels solutions with 50 ml of mineral oil. Right after pouring in to a beaker, flash freeze it with liquid nitrogen then place them into freezer. (3 freeze thaw cycle)
