Lysate sensitivity calculation

WebGel-clot LAL reagents are supplied with a specified lysate sensitivity or lambda (λ). Lysate sensitivity is the minimum concentration of endotoxin required to generate a gel-clot. Samples, standards or controls are mixed with the LAL reagent in an endotoxin-free glass test tube and incubated undisturbed at 37 ± 1 °C for 60 ± 2 minutes. WebThe sensitivity of the assay can be calculated based on the endpoint titer and the initial concentration of the labeled lysate. A higher endpoint titer indicates a more sensitive …
