  • Description

    The Pape fragment 4 peptide is a component identified in the venom of the scorpion Tityus serrulatus. It is derived from the larger Pape protein, which is characterized by repetitive proline- and alanine-rich motifs. This fragment, along with other related peptides, was sequenced using MALDI-TOF-TOF tandem mass spectrometry. The presence of multiple Pape-derived fragments in the venom suggests they are products of post-translational processing.

    These peptides are part of the diverse array of small, non-reticulated molecules found in scorpion venom. Their structural features, including a high proline content, are indicative of the repetitive sequence architecture of the parent Pape protein. The biological role of these specific fragments within the venom composition remains an area for further investigation.

  • 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.
