Tris buffer for adjusting the sample pH

Pyrogen-free (endotoxin-free) Tris buffer to adjusting the pH of the lal endotoxin test samples.

1. Product information

LAL testing microbiology detection of endotoxin by horseshoe crab blue blood lysate require certain conditions. The optimal pH for the endotoxin testing LAL reagent and endotoxin reaction is in the range of 6.0 to 8.0. If the endotoxin detection test sample pH is out of this range, the pH may be adjusted using an acid, base, or endotoxin free suitable buffers. The Acids and bases may be prepared from concentrates or solids with LAL Reagent Water in containers free of detectable endotoxin. Buffers must be validated to be free of detectable endotoxin and interfering factors. Using 50mM Tris buffer to dissolve or dilute the test samples is a convenient way to adjust the reaction pH. 

2. Product parameter

Endotoxin level < 0.005EU/ml 

3. Product features and application

Adjust the pH of LAL endotoxin testing in an easy step. Use Tris buffer to dilute the test sample, overcoming the inhibition of LAL endotoxin testing by adjust the reaction pH to the range of pH 6.0-8.0.
