产品介绍
Transdermal Peptide Disulfide (TD 1 Disulfide(peptide)) 是由 11 个氨基酸组成的多肽，可以与Na+/K+-ATPase beta-subunit (ATP1B1)结合，主要与ATP1B1的 C 末端相互作用。Transdermal Peptide Disulfide 能够增强一些大分子在皮肤中的传递。
生物活性

Transdermal Peptide Disulfide (TD 1 Disulfide(peptide)) is a 11-amino acid peptide, binds toNa+/K+-ATPase beta-subunit (ATP1B1), and mainly interacts with the C-terminus ofATP1B1. Transdermal Peptide Disulfide 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].

Peptide Solubility and Storage Guidelines:

1.  Calculate the length of the peptide.

2.  Calculate the overall charge of the entire peptide according to the following table:

 ContentsAssign value
Acidic amino acidAsp (D), Glu (E), and the C-terminal -COOH.-1
Basic amino acidArg (R), Lys (K), His (H), and the N-terminal -NH2+1
Neutral amino acidGly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q)0

3.  Recommended solution:

Overall charge of peptideDetails
Negative (<0)1.  Try to dissolve the peptide in water first.
2.  If water fails, add NH4OH (<50 μL).
3.  If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>0)1.  Try to dissolve the peptide in water first.
2.  If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3.  If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0)1.  Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2.  For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.
