Leading provider of Limulus Amebocyte Lysate (LAL) reagents for endotoxin assay. LAL test is the best test for bacterial endotoxin (pyrogen) contamination in intravenous drugs, vaccines, and medical devices before the product release. We is the first manufacturer licensed by China FDA to manufacture TAL for use as an endotoxin quality control test in the pharmaceutical and medical device markets.

1. Product information

Chromogenic End-point LAL endotoxin testing assay is a fast measurement for endotoxin pyrogen testing quantification. The endotoxin in the sample activates a cascade of enzymes in LAL, the activated enzyme splits the synthetic substrate, releasing a yellow-colored product with maximum absorbance at 405nm. The yellow product can further react with diazo reagents forming purple product with maximum absorbance at 545nm. The absorbance of both yellow product and purple product are proportional to endotoxin levels, therefore, endotoxin is quantified. By adding diazo coupling reagent, the sensitivity of the assay is increased to 0.01EU/ml. A regular spectrophotometer or plate reader with 545nm or 540nm is required for the assay. This limulus amebocyte lysate assay kit contains LAL reagent, chromogenic substrates, stop reagents, Control Standard Endotoxin, LAL reagent water and diazo coupling reagents. This LAL endotoxin testing kit is suitable to be used in endotoxin testing for medical devices.

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

The End-point Chromogenic endotoxin test LAL kit with diazo reagent for the quantitative assay endotoxin using a standard spectrophotometer. In 16 minutes, the endotoxin level could be determined at a sensitivity of 0.1EU/ml. No expensive kinetic instruments are required. Suitable for the endotoxin assay for research purpose, and the labs that have a standard spectrophotometer with 540-545nm lights.
