一般描述

过氧化氢(H2O2)是一种局部杀菌剂，在需氧细胞中作为有氧呼吸的副产物合成。它还可作为过氧化物酶体、线粒体或其他细胞区室中酶促反应的产物。

应用

过氧化氢溶液已用于：
  • 处理鼻上皮细胞，用于H2O2敏感性测定
  • 处理人永生化角质形成细胞系(HaCaT)和人黑色素瘤细胞系(GLL19)以诱导衰老
  • 孵育脑切片，进行溴脱氧尿苷 (BrdU)/NeuN染色
  • 细胞增殖测定，孵育体外实验所用的神经干细胞(NE-4C)

生化/生理作用

过氧化氢(H2O2)主要用于创口清洁。它可以通过氧化爆发和产生局部氧气来杀死病原体。H2O2可充当信号传导分子或第二信使。它以多种方式在基因表达中发挥关键作用。H2O2参与炎症调节。

  1. What is the molarity of the 30% hydrogen peroxide solution?

    The molarity of a 30 % hydrogen peroxide solution is 9.8 M based on a density of 1.11 g/ml.

  2. How stable is the 30 % hydrogen peroxide solution?

    Although dilute solutions of hydrogen peroxide have a limited shelf life, the 30% solution (when properly stored) has a shelf life measured in years. Please see the certificate of analysis for the recommend retest date for a particular lot of Product No. H1009.

  3. Does the hydrogen peroxide contain a stabilizer?

    This product contains 0.5 ppm stannate-containing compounds and 1 ppm phosphorus-containing compounds to stabilize the solution. 

  4. Can hydrogen peroxide be detected spectrophotometrically?

    Hydrogen peroxide has a molar extinction coefficient of 43.6 at 240 nm.

  5. What is the pH of a 30% hydrogen peroxide solution?

    The pH of a 30 % hydrogen peroxide solution is typically between 3 and 4.

  6. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.
