氯化钠-蛋白胨缓冲液(pH7.0,无菌) - Introduction
Sodium chloride-peptone buffer is a commonly used buffer with a pH of 7.0. Its main components are sodium chloride and peptone.
Nature:
1. colorless transparent liquid.
2. It has a stable pH value and can be used to adjust the pH of the solution.
3. can provide nutrients needed for cell growth.
Use:
1. In biological and biochemical experiments, it is used as a buffer for cell culture medium to provide the environment required for cell growth.
2. can be used for protein and enzyme dilution, preservation and stability testing experiments.
Preparation Method:
1. prepare a certain concentration of sodium chloride and peptone solution.
2. mix sodium chloride solution and peptone solution according to a certain proportion, and adjust pH at the same time until the pH value reaches 7.0.
3. Filter and sterilize to obtain sterile sodium chloride-peptone buffer.
Safety Information:
1. use should be careful to prevent ingestion, inhalation or contact with eyes and skin. In case of accidental contact, rinse immediately with plenty of water.
2. Long-term exposure to the air can cause peptone degradation, so it should be stored in a dry, cool place.
3. Be careful to avoid mixing with other chemical substances to avoid reaction or danger.
