The specific horseshoe crab reagent is also called the G factor horseshoe crab reagent/specific endotoxin detection reagent, TAL-ES-Test. The specific horseshoe crab reagent is a G-factor bypass inhibitor added to the formula of the horseshoe crab reagent, so that the horseshoe crab reagent does not produce a false positive reaction to the (1,3)β-D-glucan, and the detection result is more accurate and reliable.
