Carboxymethyl Cellulose (CMC) is an anionic cellulose-based substance and a thickener, often referred to as industrial monosodium glutamate. Its viscosity varies with temperature changes. It has a CAS number of 9000-11-7 and a molecular weight of 240.21. CMC is readily soluble in water, forming a transparent solution with a certain viscosity, and it exhibits properties such as thickening, suspending, emulsifying and stabilizing effects.
This Carboxymethyl Cellulose Solution (4%) is processed by autoclaving sterilization. A small amount can be added to suspension culture media or used according to specific experimental requirements to increase the viscosity of the culture media. This reagent is for research use only (RUO) and is not suitable for clinical diagnosis or any other purposes.
Operating Procedures (For Reference Only)
Operate in accordance with specific experimental requirements and dilute the solution to an appropriate concentration before use.
Precautions
1. Carboxylmethyl Cellulose Solution (4%) is sterile, please ensure sterile operation.
3. Please use the reagent as soon as possible after opening to avoid affecting subsequent experimental results.
4. For your safety and health, wear a lab coat and disposable gloves during operation.
