Product Description:

Follistatin 344 is a synthetic peptide fragment modeled on a defined region of the human follistatin protein, a naturally occurring binding protein. In laboratory research settings, follistatin-derived peptides are utilized for the study of protein–protein interactions and binding characteristics within controlled experimental systems. Supplied as a lyophilized powder, Follistatin 344 is intended strictly for controlled in vitro laboratory research and analytical applications. It is not designed for clinical, diagnostic, or therapeutic use.

Research Applications:

Follistatin 344 is utilized in controlled laboratory research settings for applications such as:

• Investigation of protein–protein binding interactions in defined assay systems
• Analytical evaluation of interaction dynamics between binding proteins and target molecules
• Examination of peptide behavior in biochemical and in vitro assay environments
• Characterization of interaction profiles within controlled experimental models

Storage and Handling:

• Store lyophilized powder at −20 °C until use
• Once reconstituted, store at 2–8 °C and use promptly
• Avoid repeated freeze–thaw cycles
• Maintain aseptic laboratory technique during handling

Product Specifications:

• Purity: ≥99% (HPLC and Mass Spectrometry verified)
• Appearance: Lyophilized white to off-white powder
• Solubility: Soluble in mildly acidified aqueous solutions (e.g., acetic-acid–based laboratory buffers)
