Kinetic Chromogenic Method: LAL Reagent from China Suppliers and Factory for Quantitative BET Applications

The Kinetic Chromogenic Method is an advanced, sensitive technique designed for the quantitative detection of bacterial endotoxins, specifically lipopolysaccharides found in the cell walls of Gram-negative bacteria. This method is crucial for ensuring the safety of pharmaceuticals, medical devices, and biological products, as endotoxins can lead to severe pyrogenic reactions, including fever and shock in humans.

Our kinetic chromogenic endotoxin assay, produced in our China-based factory, employs a co-lyophilized lysate that contains Limulus Amebocyte Lysate (LAL) combined with a chromogenic substrate. This innovative assay utilizes a kinetic microplate reader to accurately measure the rate of color development over time when the lysate is mixed with your samples. The reader monitors absorbance changes at a wavelength of 405nm, maintaining a constant temperature of 37℃ to ensure optimal results.

The speed of color formation in this assay is directly proportional to endotoxin concentration, allowing for precise measurements: higher concentrations of endotoxins lead to a quicker reaction and a faster achievement of a predetermined absorbance threshold. Please note, this product is not registered with the U.S. FDA and is intended for research use only if utilized in the U.S. We are proud to be among the leading suppliers of high-quality endotoxin detection products from our factory in China.
