Safety & Handling
Avoid freeze/thaw cycles.
This protein was produced in E. coli. 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.
This protein spans amino acids 1-351(end). 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 for the differentiation of hydroxymethylcytosine (HMC) from methylcytosine in DNA, via glucosylating HMC and protecting HMC from endonuclease cleavage. Refer to the product datasheet for validated protocols and recommended assay conditions. Contact BioHippo technical support for application-specific guidance.
At least 6 months at -80°C. 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.
