Overview
Surfactant S9, (Tetronic 1307), is a copolymer of epichlorohydrin, epoxyethane, and ethylene diamine, which is a typical zwitterionic surfactant. Its HLB value is greater than 24, making it a rare water-soluble surfactant within the scope of immunochromatography technology. The role of surfactant S9 in rapid diagnostic test strip products: n1 reduces the absorption of the tested substance and gold standard by the NC membrane, with a clean background and no T-line whitening phenomenon. n2. Adding an appropriate amount of surfactant S9 can improve sensitivity. n3. S9 is non hemolytic and does not have hemolytic effects
Product Details
Surfactant S9， （Tetronic1307)， It is a copolymer of epoxy propane, epoxy ethane, and ethylene diamine, which is a typical zwitterionic surfactant. Its HLB value is greater than 24, making it a rare water-soluble surfactant within the scope of immunochromatography technology.
Application of surfactant S9 in rapid diagnostic test strip products:
1. Reduce the absorption of the detected substance and gold standard by the NC membrane, with a clean background and no T-line whitening phenomenon;
2. Adding an appropriate amount of surfactant S9 can improve sensitivity to a certain extent, which has a color enhancing effect (increasing line intensity); 3，S9 is non hemolytic, does not have hemolytic effects, does not cause the release of red blood cells, and has a red background on the running board. It is a very good choice for whole blood testing products.
Advantages of Surfactant S9
Good interfacial activity, no hydrophobic surface will be formed whether adsorbed onto positively or negatively charged interfaces; Combining the advantages of both anionic and cationic surfactants, without cloud point phenomenon, and less susceptible to the influence of inorganic electrolytes;
Good emulsifying ability, dispersibility, and anti-static effect;
Based on the above characteristics, surfactant S9 has a wider application potential in many fields than non-ionic surfactants, and its application frequency in rapid diagnosis test strip products is slightly higher than other surfactants.
