产品描述

 

 

 

*近的研究表明,硫化氢H2S在生物医学和生物方面有一个显着的信号作用。尤其是在哺乳动物心血管系统中产生硫化氢可导致血管扩张、血压降低。

在研究问题中有一个相对较新的发现,那就是在生物介质的气体信号分子中可以很**地测量H2S浓度。以前使用的*谱法和色谱法不仅受到明显的干扰,而且还需要辛苦地做密集样本的制备程序工作,这样的制备程序工作会导致H2S在样本中消失。

*近,由杨等人发表在科学杂志的的一项研究采用了独特的方法来测量硫化氢浓度。论文题为H2S作为生理舒张:高血压小鼠胱硫醚-酶缺失,利用了Lazar公司实验室,在洛杉矶公司开发了一种微型硫化氢电*。

这种独特的电*是同类产品中*小的离子电*,可以测量低到10微升样品,如96孔板。H2S可以测量到小于0.1微摩尔浓度(小于100纳米的摩尔)的样品。样品制备简单,直接在96孔板或其他微量样品容器中测量,从而*大程度减少H2S的流失以及提高测量精度。与其他方法不同的是,这种微电*测量方法没有已知的干扰。

Recent studies have shown Hydrogen sulfide (H2S) to have a significant signaling role in biomedicine and biology. In particular, H2S, which is produced in the cardiovascular system of mammals, was found to lead to dilation of blood vessels and the lowering of blood pressure.

One of the problems in studying this relatively newly discovered gaseous signaling molecule is accurately measuring H2S concentration in biological media. Polarographic and chromatographic methods, which were previously used, not only suffer from significant interferences, but also require labor intensive sample prep procedures which can lead H2S loss from the sample.

A recent study by Yang* et al just published in SCIENCE uses a unique method to measure H2S concentration. The paper entitled "H2S as a Physiologic Vasorelaxant: Hypertension in Mice with Deletion of Cystathionine -Lyase" uses a micro H2S electrode developed by LAZAR RESEARCH LABORATORIES, INC., Los Angeles, CA.

This unique electrode is the smallest ion electrode of its kind and can measure volumes down to 10 microliters in samples such as 96 well plates. H2S can be measured down to less than 0.1 Micro Molar concentration (less than 100 nano Molar). Sample prep is simple and done directly in the 96 well plate or other micro sample container thereby minimizing H2S loss and increasing accuracy. Unlike other methods, this micro electrode measurement method has no known interferences.

*Yang et al, Science, Physiologic Vasorelaxant: Hypertension in Mice with Deletion of Cystathionine -Lyase",Science, Vol. 322, No. 5901, pp. 587-590, 2008 (Science issue of 24 October 2008)

Unique features of the ArrowH2S™ Hydrogen Sulfide Measurement System

  • Measure micro samples- Measure samples as small as 10 microliters in samples such as 96 well plates
  • Low detection limit- Measure H2S concentrations as low as 0.1 micro Molar (100 nano Molar)
  • Simple sample prep- one step sample prep done directly in the micro sample container
  • Cost effective- significant savings over other techniques such as chromatography and polarography
  • Use directly with your PC or laptop- Connects directly to your USB port for logging, graphing, and data recording directly on your PC
  • No known interferences unlike chromatography and polarography
