Description
PURPOSE
The entry of endotoxins into the bloodstream via injection or implantation can cause fever and/or shock, so the determination of bacterial endotoxins in drugs and medical devices is critical. The LAL test is the most sensitive method for the detection of bacterial endotoxins. Using «ALPYR Test» Gel clot test Standard kit allows to determine the endotoxin of all Gram-negative bacteria by gel clot test. The kit contains a LAL reagent in which carboxymethylcurdlan is lyophilised along with lysate, which prevents activation of the LAL reagent by β-glucans and makes it fully endotoxin-specific.
The kit contains all the necessary components to perform a gel clot test:
| Component name | Quantity per set |
| LAL reagent 0.03 EU/ml, 5.2 ml/vial | 6 vials |
| Control Standard Endotoxin | 1 vial |
| BET water 50 ml | 6 vials |
| Test tubes 10x75 ml, 50 pieces/pack | 6 packs |
| Test tubes 13x100 ml, 30 pieces/pack | 6 packs |
PRINCIPLE OF METHOD
The principle of the method is based on the ability of amoebocyte lysate from the haemolymph of horseshoe crabs (Limulus polyphemus) to react specifically with endotoxins of Gram-negative bacteria (lipopolysaccharides). The reaction of endotoxin and lysate results in a transparent reaction mixture that becomes cloudy or forms a solid gel, which serves as an indicator of the presence of endotoxin. Endotoxins can be detected by limit test or quantitative method.
