产品概述

最近的研究发现，过硫化物(Persulfide)和多硫化物(Polysulfide)等硫烷硫(Sulfane Sulfur)是生物体内的一种新型信号分子。这一类活性硫烷硫分子可以通过硫化氢释放和储存，并且与蛋白质的硫醇(Thiol)为目标的一系列信号传递(如蛋白质的巯基化等)密切相关，因此受到了广泛关注。不仅如此，过硫化物和多硫化物的还原性甚至高于半胱氨酸(Cysteine)和谷胱甘肽(Glutathione)等生物体内常见的具有还原性的物质，对维持体内的氧化还原平衡也非常重要。

Sodium polysulfide (Na2Sn)是诸多硫烷硫供体中结构最简单的一种，它在水溶液中可以随着pH的变化生成拥有多种结构的多硫化氢(Hydrogen Polysulfide, H2Sn, n≥2)。本产品是专门用于研究过硫化物、多硫化物等活性硫烷硫分子在生物体内相关通路中作用的试剂。

生物活性

Transdermal Peptide Disulfide TFA (TD 1 Disulfide(peptide) TFA) is a 11-amino acid peptide, binds to Na+/K+-ATPase beta-subunit (ATP1B1), and mainly interacts with the C-terminus of ATP1B1. Transdermal Peptide Disulfide TFA can enhance the transdermal delivery of many macromolecules[1].

体外研究
(In Vitro)

In the presence of Transdermal Peptide Disulfide, because of the specific binding of Transdermal Peptide Disulfide to ATP1B1, cells will upregulate the level of ATP1B1 to maintain function and structure; as a result, the expression of ATP1B1 increases. However, as time goes on, some Transdermal Peptide Disulfide molecules may be transported into cells by endocytosis; consequently, the expression of ATP1B1 then decreases. The interaction between Transdermal Peptide Disulfide and ATP1B1 changes not only the expression of ATP1B1, but also the localization of ATP1B1 and then the structure of the epidermal layer. This interaction can be attenuated by inhibitors or competitors, which would result in the reduced delivery of macromolecular drugs across the skin[1].
