Drug Target Assay Kit

Guanylate kinase is essential for guanine nucleotide supply. It moves a phosphate from ATP to GMP, giving GDP and ADP, and is an attractive antibacterial target. This kit measures the ADP formed.

Pack Sizes

Both sizes include the E. coli guanylate kinase. The only difference is the number of assays: GMK100KE provides reagents for 100 assays and GMK500KE for 500 assays (384-well format), with component volumes scaled accordingly.

100 assays (GMK100KE) 100 assays; enzyme included
500 assays (GMK500KE) 500 assays; enzyme included

Kit Components

Component 100 assays (GMK100KE) 500 assays (GMK500KE)
10 x Assay buffer 600 µl 2000 µl
100 x GMP 35 µl 170 µl
100 x E. coli GMP kinase 35 µl 170 µl
100 x ATP 35 µl 170 µl
100 x MUK Reagent A 35 µl 170 µl
100 x MUK Reagent B 35 µl 170 µl
10 x Fluorescence dye 350 µl 1700 µl

The 1 x buffer contains 50 mM Tris-HCl pH 8.0, 3 mM MgCl2, 0.2 mM EDTA, 0.5 mM DTT, 50 mM NaCl and 0.003% Brij-35.

Assay Principle

The kit measures the ADP formed in the kinase reaction (GMP + ATP -> GDP + ADP). MUK Reagents A and B and a fluorescence dye turn the ADP into a fluorescence signal read at Em 535 nm with excitation at 485 nm.

Q.What does this kit measure?
A.It measures the activity of E. coli guanylate kinase by detecting the ADP produced when the enzyme phosphorylates GMP with ATP. The fluorescence readout supports activity tests and inhibitor IC50 measurements.
Q.What is the difference between the options?
A.Both sizes include the E. coli guanylate kinase. The only difference is the number of assays: GMK100KE provides reagents for 100 assays and GMK500KE for 500 assays (384-well format), with component volumes scaled accordingly.
Q.Is a protocol available?
A.Yes. The manufacturer's protocol (E. coli Guanylate Kinase Assay, linked under Documents) covers catalog # GMK100KE, GMK500KE.
Q.How long does the assay take?
A.About 62 min (2 min pre-incubation + 60 min reaction, then add dye and read). See the protocol for the exact steps.
Q.How should the kit be stored?
A.The E. coli Guanylate Kinase Assay Kit Plus is shipped frozen. Please contact us for long-term storage conditions.
