- Hydroxyethyl starch 130/0.4
The molecular weight distribution ranges from 110 kDa to 150 kDa, with a degree of substitution of 0.37-0.43. Hydroxyethyl starch 130/0.4 has good safety and scalability in clinical practice by reducing molecular weight and narrowing the molecular weight distribution, lowering substitution levels, and changing substitution modes (C2/C6). - Hydroxyethyl starch 200/0.5
Hydroxyethyl starch 200/0.5 raw material is prepared by acid hydrolysis and hydroxyethyl conversion of high branched chain starch, with a molecular weight distribution of 170 kDa -230 kDa and a degree of substitution of 0.46-0.54. It belongs to the category of medium molecular weight low degree of substitution hydroxyethyl starch. The chemical name is poly (O-2-hydroxyethyl) starch, commonly known as hydroxyethyl starch 200/0.5.Hydroxyethyl starch 200/0.5 injection has a fast and strong dilating effect, which can maintain a moderate dilating effect for up to 4 hours. It can be completely cleared from the kidneys,accumulates less in plasma and tissues, has the least impact on coagulation function, and can improve microcirculation. Hydroxyethyl starch 200/0.5 (HES200/0.5) injection is currently the most commonly used plasma substitute in Europe, and is the preferred drug for the treatment and prevention of hypovolemia and shock.

- Hydroxyethyl starch 480/0.7
As a high molecular weight and high degree of substitution hydroxyethyl starch 480/0.7 in the medium molecular weight hydroxyethyl starch series, its molecular weight distribution ranges from 468 kDa to 600 kDa, with a degree of substitution of 0.69-0.81. Hydroxyethyl starch 480/0.7 has stronger expansion capacity and is currently mainly used in the United States, Europe, and some Central Asian countries. In order to improve the hydroxyethyl starch product line and meet the emergence of new plasma substitute products and the personalized needs of customers, Huakeda Life Science and Technology Company will soon complete the research on hydroxyethyl starch 480/0.7 and its compound electrolyte preparation within the year, and strive to cover the entire range of high-end plasma substitute products within two years. - Narrow distribution hydroxyethyl starch
Narrow distribution hydroxyethyl starch can serve as a novel medium for density separation of blood cells in animals or humans. Can be used as a substitute for sucrose or dextran to prepare cell density separation solutions and separate various cells. A specific weight average molecular weight with a narrow molecular weight distribution makes it easy to achieve the density gradient of the cell separation solution, while also preventing cell aggregation, resulting in good cell separation efficiency.
Used for clinical diagnosis: completely separated, less likely to produce coagulation samples, avoiding non-specific binding or strong background interference.
Used for biomedicine: It can effectively obtain cell samples with high yield, high quality, and high survival rate.
