Copper Assay kit LS

(DiBr-PAESA Chromogenic method)
For the Quantitative Determination of copper in
Serum, Plasma or Urine
PRINCIPLE
In this procedure Copper dissociated from proteins, in particular conditions of ionic strength, gives with Di-Br-PAESA a stable colored complex, which intensity of color is proportional at the concentration of Copper in the sample.
Kit contents
Chelate color (DI-Br-PAESA) 2×25 mL
Copper Standard (100.0 μg/dL) 1× 5 mL
Expiration date and preservation conditions
Expiration: 1 year from the date of manufacture.
Storage conditions: Store at 2-8°C. Don’t freeze. 

Zinc Assay kit LS

(5-Br-PAPS) Chromogenic method
For the Quantitative Determination of zinc in
Serum, Plasma or Urine
Principle
In this procedure is a direct colorimetric assay kit without
Deproteinization of the sample. At alkaline pH, in a buffered
media, zinc reacts with the specific complex, forms a stable
colored complex. The color intensity is proportional to the
amount of zinc present in the sample.
Kit contents
Chelate color (5-Br-PAPS) 2×25 mL
Zinc Standard (200 μg/dL ) 1× 5 mL
Expiration date and preservation conditions
Expiration: 1 year from the date of manufacture.
Storage conditions: Store at 2-8°C. Don’t freeze. 

Magnesium Assay kit LS

(Xylidyl Blue) Chromogenic method
For the Quantitative Determination of Magnesium in
Serum, Plasma or Urine
Principle
In this procedure magnesium and Xylidyl Blue combine under alkaline
conditions to form a water soluble red-purple chelate with an absorption
maximum at 520 nm. Interference from calcium is prevented by the presence of GEDTA (Glycoletherdiamine-N, N, N'. N' - tetra acetic acid) which completely masks a similar colored calcium chelate. The magnesium chelate color is stable, and the assay is not subject to interference from other inorganic ions.
Kit contents
Chelate color (Xylidyl Blue) 2×25 mL
Magnesium Standard (2.0 mg/dL) 1× 5 mL
Expiration date and preservation conditions
Expiration: 1 year from the date of manufacture.
Storage conditions: Store at 2-8°C. Don’t freeze.
