Catalog number: 11344041. Gibco™ HEPES (N-2-Hydroxyethylpiperazine-N-2-Ethane Sulfonic Acid) is a zwitterionic organic chemical buffering agent commonly used in cell culture media. The addition of 10 – 25 mM HEPES provides extra buffering capacity when cell culture requires extended periods of manipulation outside of a CO 2 incubator. HEPES는 온도가 낮을수록 해리가 감소한다는 점에서 물과 비슷하다. 이러한 면에서 HEPES는 저온에서 효소 의 구조와 기능을 유지하는데 효과적인 완충제이다. 연구에 따르면, 환경의 빛에 노출 됐을때, HEPES가 과산화수소를 생성하여 광독성이 있다고 하는데 ...HEPES has been described as one of the best all-purpose buffers available for biological research. At biological pH, the molecule is zwitterionic, and is effective as a buffer at pH 6.8 to 8.2 (pKa 7.55). It is typically used in cell culture at concentration between 5mM to 30 mM. HEPES has been used in a wide variety of applications, including ... HEPES (Fine White Crystals/Molecular Biology), Fisher BioReagents™ Commonly used buffering agent See promotional offers below.
