Concentration assays for Citrate / Tartrate

 

 

 

1.  Citrate

 

Citrate is an important biomolecule and popular additive in pharmaceutical products. The Citrate Assay Kit is for measurement of sub-millimolar to low millimolar concentrations of citrate. 

The assay is based on increase of the optical density at 490 nm (OD490) of the kit reagent upon binding to citrate. The assay is compatible with Tris-HCl buffers. It is not compatible with phosphate buffers, polycarboxylic acids or other poly acids.

 

 

 

 

 

 

 

 

Citrate Assay kit (Catalog No CIT100) 

Includes 1.5 ml of Reagent A, 1.5 ml of 10 x Reagent B and 0.2 ml of 100 mM ammonium citrate. It is for 100 assays using 96-well plates. Cuvettes may also be used for measurements.

 

 

 

 

2.  Tartrate

 

Tartrate is a common additive in pharmaceutical products and food products. The Tartrate Assay Kit is for measurement of sub-millimolar to low millimolar concentrations of tartrate. 

The assay is based on increase of the optical density at 490 nm (OD490) of the kit reagent upon binding to tartrate. The assay is compatible with Tris-HCl buffers. It is not compatible with phosphate buffers, polycarboxylic acids or other poly acids.
