Biological Activity
4-Nitrophenyl palmitate serves as a colorimetric substrate for lipase and esterase, enabling the quantification of enzyme activity through the release and colorimetric detection of 4-nitrophenol at 410 nm following enzymatic hydrolysis. This compound facilitates the characterization of enzyme activity across diverse bacterial and mammalian sources, including Burkholderia and porcine pancreatic lipases.
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
After the stock solution is prepared, it is typically stored at -80°C and can be kept for over 1 year. It is recommended to aliquot to avoid repeated freeze-thaw cycles. For frequent use, it can be stored at 4°C for over a week.
Due to the small pack, the powder may be highly dispersed during shipping due to static electricity and may adhere to the vial. Please centrifuge and add an appropriate solvent to fully dissolve the product and prepare the stock solution.
