Recombinant animal-free reagents in the bacterial endotoxins test - USP
WebMix BCA Reagent A with BCA Reagent B at a 50:1 ratio (50:1, Reagent A:B). This is your working reagent. Be sure to make enough for at least 10 wells (see step 3). Add 200uL of working reagent to each well. Cover the plate and mix by gently tapping the edge. Incubate at 37°C for 30 minutes. Measure the absorbance at 562 nm. Constructing a ...

WebAdvantages of the Amplex UltraRed reagent over chromogenic reagents—Table 10.5 Peptidases and proteases play essential roles in protein activation, cell regulation and signaling, as well as in the generation of amino acids for protein synthesis or utilization in other metabolic pathways. WebAn example of acceptance criteria of measured endotoxins activity using recombinant and naturally derived lysates might be the following: The measured activity of a sample containing endotoxins using a recombinant reagent method should fall within 50%-200% of the measured activity in the same sample tested using natural lysate as described in <85>. WebThe chromogenic nature of the assay makes it the most appropriate choice for testing small volume parenterals, vaccines, antibiotics and biologicals. It is also ideally suited to testing inhibitory products, which may interfere … rocky mountain and sheet metal
