Source: 1mg kit, 1mg/vial x 1, lyophilised. Purity by HPLC/MS COA.

Storage & Handling

Reference material is supplied lyophilised in sealed vials. Recommended laboratory handling: store sealed vials at -20°C protected from light and moisture. Once reconstituted in a research-grade aqueous buffer, hold at 2–8°C for short-term use or aliquot and store at -20°C or below to limit freeze-thaw cycles. Allow vials to equilibrate to room temperature before opening to prevent condensation.

Reconstitution buffer, concentration, and assay format are determined by the receiving laboratory’s protocol. Syther Peptides does not supply usage protocols.

Quality & Compliance

Certificate of Analysis

Purity and identity are confirmed by Certificate of Analysis (HPLC / MS), available on request alongside the quote. The COA documents batch number, identity confirmation method, purity by HPLC peak-area, and reference to the analytical method used.
