Sialyltransferase Activity Kit Summary

View Full Assay Principle
The Sialyltransferase Activity Kit (Catalog # EA002) provides a simple, non-radioactive high-throughput compatible format for assaying the enzyme activity of all sialyltransferases regardless of different acceptor substrates. This kit utilizes the 5’-nucleotidase CD73 as a coupling phosphatase to remove inorganic phosphate quantitatively from the leaving nucleotide cytidine 5’-monophosphate (CMP) that is generated during sialyltransferase reactions.

 

Features

  • Applicable for all sialyltransferases
  • Non-radioactive
  • No time-consuming separation steps (e.g. column chromatography)
  • Provides accurate kinetic analysis of sialyltransferase reactions
  • Amenable to high-throughput analysis

Kit Contents

  • CHO cell-expressed Recombinant Human CD73
  • CMP
  • Phosphatase Buffer 2
  • 100 mM MnCl2
  • Phosphate Standard
  • Malachite Green Reagents A & B

Data Example

Activity of ST6GALNAC2

Activity of ST6GALNAC2View Larger Image

The ability of Recombinant Mouse ST6 Sialyltransferase 2/ST6GALNAC2 (Catalog # 6468-GT) to transfer Neu5Ac (sialic acid) from CMP-Neu5Ac to bovine asialofetuin was measured using the Sialyltransferase Activity Kit (Catalog # EA002). The activity was plotted against enzyme input, and the specific activity of ST6GALNAC2 was determined to be 774 pmol/min/μg.

FAQs

  1. Does the Malachite Green Phosphate Detection Kit (DY996) detect both pyrophosphate (diphosphate) and free phosphate (monophosphate)?

    • The Malachite Green Phosphate Detection Kit measures free inorganic phosphate in aqueous solutions. The assay principle is based on complex formation between malachite green molybdate and free phosphate under acidic conditions. Lipid bound, protein-bound, pyrophashate and other condensed phosphates must be hydrolyzed prior to measurement in the malachite green assay.
