Non-inactivated

Hank's buffer, phenol red, BSA, preservatives, etc.

①New formula, more stable

②Maintain the biological activity of samples, culture, antigen and antibody detection, nucleic acid detection, etc.

Cultivation, antigen and antibody detection, nucleic acid detection, etc.

S/D inactivated type

Hank's buffer, detergent S/D, nuclease inhibitor, protective agent, preservative, EDTA, TCEP, etc.

①Organic solvent/detergent (S/D) destroys the lipid membrane of the virus and inactivates the virus

②The structure of the virus is basically complete, and the storage time is long

Protein analysis and nucleic acid detection

Strong inactivation type

Tris buffer, hydrochloric acid, TCEP, EDTA, NaCkI, KCl, etc.

①Strong protein denaturant to release nucleic acid

②Seamless connection with nucleic acid extraction

Only applicable to nucleic acid testing Sample storage
