Cat. No.: C745028
COA
Cre Recombinase
AVAILABLE TO ORDER
GRADE & PURITY Animal Free ? Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material. Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. EnzymoPure™ ? EnzymoPure™ — Aladdin's line of high-quality enzymatic solutions. Use when enzyme purity and defined activity drive assay or process performance. Sterile ? Sterile grade — processed and verified free of viable microorganisms. Use directly in aseptic procedures and cell culture without further sterilization. 1.0 U/μL
Accession #
Q5QBM7
Expression system
E. coli
Bioactivity
One unit is defined as the amount of enzyme required to achieve the maximum site-specific recombination of 250ng of control DNA in 30 minutes at 37ºC in a 50μl reaction system. The maximum recombination can be analyzed by agarose gel electrophoresis or by screening on the corresponding resistance plates after transformation of the reactions.
