GST Control protein

Glutathione-S-Transferase (GST) Control Protein was purified by chromatography from E. coli preparations. Assay by immunoelectrophoresis resulted in a single precipitin arc against Anti-GST antibody. Analysis by SDS-PAGE resulted in a pattern consistent with purified GST and an estimated purity greater than 90%.

Store vial at -20 °C prior to opening. Aliquot contents and freeze at -20 °C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4 °C as an undiluted liquid. Dilute only prior to immediate use.

GST Control Protein is suitable for use as a control in affinity purification and in western blot immunoassays and has been tested in SDS-page. Optimal concentration should be determined by the researcher. Expect ~25.5 kDa in SDS-PAGE.
