Product Description
Transdermal Peptide Disulfide (TD 1 Disulfide(peptide)) is a polypeptide consisting of 11 amino acid (AA)s, which can bind to Na+/K+-ATPase beta-subunit (ATP1B1) and mainly interacts with the C-terminus of ATP1B1. Transdermal Peptide Disulfide enhances the delivery of some large molecules through the skin.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Cells will upregulate the amount of ATP1B1 to preserve function and structure in the presence of Transdermal Peptide Disulfide due to the particular binding of Transdermal Peptide Disulfide to ATP1B1; thus, the expression of ATP1B1 increases. But with time, some Transdermal Peptide Disulfide molecules would enter cells through endocytosis; as a result, ATP1B1 expression would decline. The way Transdermal Peptide Disulfide and ATP1B1 interact modifies not only the expression of ATP1B1, but also where it is located and ultimately the epidermal layer's structure. Inhibitors or competitors may lessen this interaction, which would decrease the amount of macromolecular medications that are delivered via the skin[1].

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (Please use freshly prepared in vivo formulations for optimal results.)

5 mM 0.1885 mL 0.9424 mL 1.8847 mL
10 mM 0.0942 mL 0.4712 mL 0.9424 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
