Batch to batch variation of the purity
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.
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
Concentration (stock) × Volume (stock) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1 V1 = C2 V2
This equation is commonly abbreviated as: %(w/v) = Weight of solute(g) / Volume of solution(mL) × 100%
GRAVY = grand average of hydropathy
