WebHEPES-buffered saline (HBS) solution: Prepare 2 × HBS stock by adding the following to 400 ml dH 2 O: 50 ml 1 M HEPES, 28 ml 5 M NaCl and 1.5 ml 0.5 M Na 2 HPO 4. After adjusting the pH to 7.05–7.10 with 5 M and 1 M NaOH, bring the total volume to 500 ml with dH 2 O. •. WebTyrode's solution is a solution that is roughly isotonic with interstitial fluid and used in physiological experiments and tissue culture. It resembles lactated Ringer's solution, but contains magnesium, a sugar (usually glucose) as an energy source and uses bicarbonate and phosphate as a buffer instead of lactate.Some variations also include phosphate and …

WebProcedure. Add 2.38 g of HEPES to an appropriate beaker (100-200 mL beaker in this case). Add about 80 mL of deionized water to the beaker. Add a stir bar to the beaker and leave it on a stir plate until completely dissolved (~1 min). Begin monitoring pH of the solution. It should be acidic (pH ~5). Add one NaOH pellet to raise the pH towards 7.4. WebTE buffer is a commonly used buffer solution in molecular biology, especially in procedures involving DNA, cDNA or RNA. "TE" is derived from its components: Tris, a common pH buffer, and EDTA, a molecule that chelates cations like Mg 2+.The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
