一般描?/p>
Potassium phosphate is widely used in buffers to prepare biological samples and examine biological interactions.
应用
Potassium phosphate monobasic has been used:
- to prepare the working luminol solution to study the prooxidant activity in the chemiluminescent system luminol–H2O2
- in phosphate buffer saline (PBS) to culture embryonic stem cells (ESCs) and generate embryoid bodies
- in PBS to prepare polydimethylsiloxane (PDMS) substrate
