Trypsin ethylenediaminetetraacetic acid trypsin edta

Manufactured by Thermo Fisher Scientific
Sourced in United States

Trypsin-EDTA is a solution used to detach adherent cells from cell culture surfaces. It contains the enzyme trypsin, which cleaves cell-cell and cell-matrix adhesion proteins, and EDTA, which chelates calcium and magnesium ions required for cell-cell interactions. This solution is commonly used in cell culture procedures to enable passaging and harvesting of adherent cells.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
