Analysis of the components of serum separation gel
Serum separation gel is a chemically inert and thixotropic viscous colloid. Its density is just between the density of serum and blood clot. After centrifugation, the serum and blood clot can be completely separated. The serum is quickly separated and the material exchange between blood cells and serum is prevented, making blood testing and chemical experiments safer, faster and more convenient.
In this article, the components of the serum separation gel will be analyzed and the performance of the serum separation gel will be compared.
1. Analysis of the components of polysiloxane serum separation gel: The serum separation gel is composed of polysiloxane, silicon dioxide, diluent and additives. The main body material contains 80% to 90% of polysiloxane, 10% to 15% of silicon dioxide, and about 2% of diluents and additives. The appearance of the polysiloxane serum separation gel is a translucent, blue-colored colloid, and the drawing is not long.
2. Analysis of the composition of polyacrylate serum separation gel: The serum separation gel is composed of polyacrylate, fumed silica and additives. The polyacrylate content of the main material is 96%, the fumed silica is 3%, and the additive is 1%. The appearance of polyacrylate serum separating gel is colorless and transparent colloid, with good stringiness.
3. Orthogonal experiments on the components of the serum separation gel show that fumed silica has the greatest influence on the thixotropy and viscosity of the serum separation gel. Whether the host material can provide hydrogen bonds and the size of the polarity have a certain impact on the thixotropy of the serum separation gel. When the density of the main body material is less than 1g/cm3, the precipitated silica plays a major role in adjusting the density of the serum separation gel. The additive silane coupling agent can fine-tune the thixotropy of the serum separation gel.

HEPES, as a zwitterionic buffer, increases the osmotic pressure of the cell culture system by increasing the concentration of solution ions, maintaining normal cell morphology and function, and improving cell survival rate. Widely used in cell culture, especially under specific conditions such as tumor cell culture, it is crucial to maintain cell growth and function.
