Quality Control

Our C Protein Alpha Antigen is produced under stringent conditions to ensure batch-to-batch consistency and high biological activity. Quality is verified through a comprehensive suite of analytical techniques including electrophoresis (SDS-PAGE), HPLC for purity, and functional immunoassays to confirm antigenic specificity. A detailed Certificate of Analysis (COA) is provided with each batch, documenting purity, identity, and performance data.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below in a non-frost-free freezer. Avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature before opening to prevent condensation.
