Common pH buffer
Category : Laboratory Chemicals
CAS NO : EC NO : MF : MW : Product description : In many biological experiments, buffers are needed to maintain an effective pH value, and buffers are critical to the success or failure of the experiment. When choosing a buffer, first consider that the pH value in the experiment is consistent with the pH value range of the buffer, and consider whether the advantages and disadvantages of different buffers are suitable for your experiment. There are many types of biological buffers. In this article, we mainly discuss the preparation methods of several commonly used biological buffers. Prepare TRIS base and TRIS-HCL buffer Tris: To prepare 1 liter of 1M Tris buffer, first prepare to dissolve 121.14 grams of Tris powder in 750 mL of dH20, adjust to the desired pH value with concentrated hydrochloric acid, and fill to the final volume of 1L with dH2O. Tris HCl: To prepare 1 liter of 1M Tris HCl buffer, first dissolve 157.60 g of Tris-HCl in 750 mL of dH2O, adjust to the desired pH with 10N sodium hydroxide, and fill with dH2O to a final volume of 1L. Prepare HEPES buffer To prepare 1 liter of 1M HEPES buffer solution, first dissolve 238.3 grams of HEPES powder in 750 mL of dH2O, adjust to the desired pH with 10N sodium hydroxide, fill with dH2O to a final volume of 1L, and pass through a filter or autoclave The device is disinfected. Store the buffer at 4C. Prepare PIPES buffer To prepare 1 liter of 1M PIPES free acid buffer solution, first add 302.37 g of PIPES free acid to 600 mL of dH2O, adjust to the desired pH with 10N sodium hydroxide, and fill to the final volume of 1L with dH2O.
