WebControl standard endotoxin under the test for confirmation of labeled lysate sensitivity should be diluted with water for BET into at least four concentrations equivalent to 2λ, λ, 0.5λ and 0.25λ (λ here means the labeled sensitivity of TAL reagent and is expressed in EU/ml). http://pharmacopeia.cn/v29240/usp29nf24s0_c85.html
WebTo calculate the concentration of the undiluted, unknown sample, simply multiply by the dilution factor. So, 0.5 x 10= 5mg/ml. Protein Standard Curve or Linear Plot A common question is should you use a linear plot or a curve (a curvilinear regression). WebThe lysate sensitivity is calculated by determining the geometric mean of the endpoint. Each endpoint value is converted to log 10. The individual log 10 values are …
WebIf the sensitivity of the lysate determined in the presence of the sample solution under test of Solution B is not less than 0.5 and not greater than 2, the sample solution does not contain factors which interfere under the experimental conditions used. Otherwise, the sample solution to be examined interferes with the test. Web27 sept. 2011 · 4.5.7 Calculate the lysate sensitivity by determining the geometric mean of the endpoint. Each endpoint value is converted to log 10. The individual log 10 values are averaged, and the lysate sensitivity is taken as the antilog 10 of this average log value. The acceptable variation is one-half to two times the labeled lysate sensitivity. EXAMPLE
Web16 dec. 2024 · The gel-clot technique is used for detecting or quantifying endotoxins based on clotting of the lysate reagent in the presence of endotoxin. The minimum …
