The LAL reagent is formulated with a synthetic substrate which produces a chromophore when acted upon by endotoxin activated enzyme. The test is read at 405 nm, usually in a microplate reader. The maximum sensitivity is 0.005 EU/mL.

• Requires a microplate reader (an incubating reader is required for the kinetic method)
• Maximum sensitivity to 0.005 EU/mL
• A quantitative assay providing electronic stored data and print-outs of results
• Incubation time varies depending on the standard curve range
• Higher sensitivity allows for greater dilution to overcome interference
• The option of a diazo-coupled endpoint method (read at 540–550 nm) is available, which is useful for samples that absorb light at 405 nm

Product Description

Chromo-LAL lysate is lyophilized with substrate reagent and buffers. It is optimized for the kinetic chromogenic LAL test method in microplate readers. Chromo-LAL is a buffered, stable and robust lysate, suitable for quantitative testing of a wide range of samples.

Product Sensitivity

The sensitivity for chromogenic assays is determined by the lowest standard concentration on the standard curve used for the assay. The maximum sensitivity of Chromo-LAL is 0.005 EU/mL.
