In the sterilization process of the hemodialysis equipment system, dialysis water, dialysis concentration and dialysate that exceed the endotoxin level will bring endotoxin into the blood of uremic patients, causing endotoxemia in uremic patients. Endotoxins act on phagocytes, neutrophils, endothelial cells, platelets, the complement system and the coagulation system, histamine and kallikrein, and other biologically active substances can cause insufficient capillary perfusion of tissues and organs, resulting in hypoxia and acidosis. High concentrations of endotoxin can also activate alternative complement pathways, trigger high fever, low blood pressure and activate the coagulation system, leading to disseminated intravascular coagulation. Therefore, endotoxin must be detected and removed from the dialysate.
The sources of endotoxin pollution related to dialysis mainly include the following 3 aspects.
(1) Water pretreatment system.
(2) Reverse osmosis water transportation pipeline.
(3) In the process of preparing the dialysis concentrated solution, the contamination of the dialysis concentrated solution, the bicarbonate dialysate is very easy to grow bacteria.

Endotoxin removal is one of the most difficult tasks downstream in protein purification. At Creative BioMart, our experienced scientists will develop a customized protocol for your target protein after estimating endotoxin removal efficiency and sample recovery. We will use a combination of the following methods to ensure maximum efficiency.
The hydrophobic column interacts with nonpolar protein surfaces through van der Waals forces for endotoxin removal.
It uses composite polyacrylamide as the column, which is highly porous. Ultrafiltration results in relatively good endotoxin clearance from product solutions when the products are of low molecular weight.
The high selectivity of affinity chromatography eliminates the need for multiple purification steps and reduces production costs. At the same time, this method can remove endotoxin with high specificity and efficiency, resulting in excellent target recovery.
Creative BioMart offers a corresponding endotoxin removal service. You can purchase the corresponding endotoxin removal kit and related accessory products according to the needs of your own samples. We guarantee that all instruments, water, reagents, and consumables used in the experiment are free of endotoxins, and the experiment is conducted in a clean room to ensure that low levels of endotoxins are returned to the sample. In addition, we can also provide you with related services including:
| Project name | Endotoxin removal services in dialysate |
| Removal cycle | 5-7 days. |
| Removal purpose | In the sterilization process of the hemodialysis equipment system, the dialysis water exceeding the endotoxin level, the dialysis concentration and the dialysate will bring the endotoxin into the blood of uremic patients, causing endotoxemia in uremic patients. Therefore, the dialysis system must remove endotoxin before use. |
| Service including | Creative BioMart can screen for the source of endotoxin contamination in the production process and propose several solutions to remove endotoxin to reduce the endotoxin content in the finished product. |
