【Important Announcement】 Reupgrading of COVID-19 Test Tool: High Sensitive COVID-19 Spike Protein ELISA Kit with fg/ml Sensitivity

Abstract:     Currently, the general epidemic situation in China is steady. However, it's reported that sporadic cases appear in many places. With the decrease of the temperature, the virus activity increases. The work for preventing rebound of the epidemic is heavier. Hence, the research of COVID-19 products still has great value. The competition is intense.
