Endpoint Chromogenic Kit EC80545

Bioendo EC Endotoxin Test Kit (End-point Chromogenic Assay, Diazo Coupling) provides a fast measurement for endotoxin quantification. The endotoxin in the sample activates a cascade of enzymes in Amebocyte Lysate, the activated enzyme splits the synthetic substrate, releasing a yellow-colored item. Then the yellow item can further react with diazo reagents to form purple items with maximum absorbance at 545nm. A regular spectrophotometer or microplate reader is required to read the absorbance at 545nm.

Bioendo EC Endotoxin Test Kit (End-point Chromogenic Assay, Diazo Coupling)

1. Product Information

Bioendo EC Endotoxin Test Kit (End-point Chromogenic Assay, Diazo Coupling) provides a fast measurement for endotoxin quantification. The endotoxin in the sample activates a cascade of enzymes in Amebocyte Lysate, the activated enzyme splits the synthetic substrate, releasing a yellow-colored item. Then the yellow item can further react with diazo reagents to form purple items with maximum absorbance at 545nm. A regular spectrophotometer or microplate reader is required for the assay. The purple items are proportional to endotoxin concentration. Then endotoxin testing result is quantitative analysis. 

2. Product Parameter

Sensitivity Range: 0.01-0.1EU/ml (assay time about 46 minutes)

                             0.1-1.0EU/ml (assay time about 16 minutes)

3. Product Features and Application

Bioendo EC Endotoxin Test Kit (End-point Chromogenic Assay, Diazo Coupling) is intended for use in the In Vitro detection and quantitation of gram-negative bacterial endotoxins. The colorless artificial peptide substrate solution is added into Lyophilized Amebocyte Lysate, and then test specimen mixture. If specimen contains endotoxin, color of specimen mixture changes. The absorbance is related to the endotoxin concentration. Therefore the endotoxn levels in specimen mixture can be claculated against a standard curve. Standard spectrophotometer with 540 – 545nm filter is enough to quantify endotoxin with our EC Endotoxin Test Kit (End-point Chromogenic Assay, Diazo Coupling).

 

Note:

Lyophilized Amebocyte Lysate (LAL) reagent manufactured by Bioendo is made from amebocyte lysate derived blood of horseshoe crab.

      End-point Chromogenic Endotoxin Test Kit (without Diazo Coupling) 1. Product Information End-point Chromogenic Endotoxin Test Kit (without Diazo Coupling) is conducted by adding a colorless artificial peptide substrate solution into mixture of Lyophilized Amebocyte Lysate and test sample after a certain incubation period. If test sample contain endotoxin, a yellow color will develop in the 96 well microplate. Its absorbance (λmax = 405nm) is related to the endotoxin concentration. Endotoxin ...
