Safety & Handling
FOR RESEARCH USE ONLY (RUO). Not for diagnostic or therapeutic applications.
This protein was produced in a recombinant expression system. Expression system selection determines post-translational processing, disulfide bond formation, and co-factor incorporation — all of which affect enzymatic activity. Insect cell (Sf9) systems are preferred for kinases and multi-subunit enzymes that require phosphorylation or chaperone assistance; E. coli is used for structurally simpler proteins.
The expressed amino acid region is specified in the product description. Confirm the region includes your domain of interest — the active site, binding pocket, or substrate recognition sequence — before placing your order. Refer to the UniProt database for domain annotation.
Purity is assessed by SDS-PAGE; see the Certificate of Analysis. A gel image is provided with each lot. BPS Bioscience performs rigorous QC on each lot, including purity assessment and functional activity testing where applicable. Contact technical support if purity ≥99% is required for biophysical measurements.
Useful as a substrate for JAK2 inhibitor screening. Refer to the product datasheet for validated protocols and recommended assay conditions. Contact BioHippo technical support for application-specific guidance.
At least 12 months at -20°C. Store reconsitituted solution in aliquots at -20°C or below for up to 6 months. Avoid repeated freeze-thaw cycles — prepare single-use working aliquots. Add BSA or glycerol to aliquots if storing diluted enzyme is necessary. Typical stability is at least 6 months at −80°C.
