What is the function of the yellow separation tube for plasma free RNA?

Blood sample collection is one of the routine operations in hospitals. Medical staff often separate and store blood samples based on different blood examination items and the different additives used for blood collection. In order to facilitate the identification of blood collection vessels for different purposes, they are usually distinguished by the color of the test tube cap. For example, a yellow cap represents the addition of serum separation gel reagents to the test tube, and a green cap represents the addition of heparin substances to the test tube.

In clinical practice, plasma free RNA is a common detection item, and yellow test tubes containing serum separation gel are generally used to extract and preserve plasma proteins. Because separating gel can effectively separate serum and plasma and protect the stability of protein in plasma, it is widely used in proteomics and clinical analysis.

In addition, for different proteins, separation tubes can be used in conjunction with other stabilizers. For example, adding dipeptide carnosine IV inhibitors to the tubes can effectively protect GLP-1 from degradation, thus obtaining accurate measurement results. At the same time, it can also be used to collect and store glucagon like peptide-1, gut inhibitory peptide, glucagon and other substances. The use of the separation hose can improve the detection efficiency, facilitate the transfer and transportation of plasma samples, and ensure that the protein composition does not change.
