Product Details

Storage & Handling
Store between 2°C and 8°C. Do not freeze.

ICFC - Quality tested

Recommended Usage

Prepare fresh Transcription Factor Fix working solution by diluting the 4X Fix Concentrate (1 part) with the Fix Diluent (3 parts). 1 mL of the 1X Fix working solution is needed for each tube.

Prepare a 1X working solution of the Perm Buffer by diluting the 10X Perm Buffer with distilled water. 6.5 mL of 1X Perm Buffer is needed for each sample of tube.

NOTE: The 10X Perm Buffer may have crystallization or precipitation when it is stored at 2-8°C; however, this is normal and does not affect the buffer's performance. If there is a heavy precipitation observed after dilution to 1X working solution, it can be filtered to clarify the solution.

Application Notes

Buffer Set Contents:

  • True-Nuclear™ 4X Fix Concentrate (30 mL)
  • True-Nuclear™ Fix Diluent (100 mL)
