Product Info
DBCO-PEG4-TFP ester serves as a heterobifunctional PEG linker containing an azide-reactive DBCO click chemistry handle and an amine-reactive TFP ester that is less susceptible to undergo hydrolysis compared to NHS ester. The PEG spacer enhances the water-solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Method recognition:
Novel method
The Phytase Assay Kit is a simple, quantitative method which can be used to measure phytase activity. Analysis is based on the hydrolysis of phytic acid by phytase and quantitative measurement of the phosphate released. Results are measured using a standard UV-VIS spectrophotometer and do not require the creation of a standard curve. The Phytase method can be used to measure phytase activity in cereal, fungal and bacterial phytases, and can also be used for the analysis of phytase in animal feed samples.
