About TFA salt

Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.

Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.

Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.

In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.

Molar Concentration Calculator

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

Mass=Concentration×Volume×Molecular Weight

Dilution Calculator

Concentration (stock) × Volume (stock) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C 1 V 1 = C 2 V 2

Concentration (stock) C1 ×Volume (stock) V1 =Concentration (final) C2 ×Volume (final) V2

Percent Concentration Calculator

This equation is commonly abbreviated as: %(w/v) = Weight of solute(g) / Volume of solution(mL) × 100%

Weight of Solute=Volume of solution×Concentration (%)
