Important Notes
- Please separate bulk reagent in several tubes when received.
- Advise to centrifuge it to aggregate the materials.
- NO violent shaking.
- If there’s any sediment after redissolving the reagent, you can shake, centrifugal and filter it, in most circumstances, it does not affect the performance.
Safety Note: For research only, inedible, no direct touch by skin.
