产品简介

背景描述	SARS‑CoV‑2 is a kind of coronavirus which full name is severe acute respiratory syndrome coronavirus 2. SARS‑CoV‑2 is contagious that causes the respiratory diseases and lung diseases which make difficulty breathing. SARS‑CoV‑2 do the spillover event in 2019 because it has genetic diversity. SARS-CoV-2 is composed by four subunits (spike, envelope, membrane and nucleocapsid proteins). Its RNA genome is encapsulated with nucleocapsid protein. The viral envelope is comprised of spike, envelope and membrane protein. SARS‑CoV‑2 has high affinity to ACE2, which is highly expression in intestines, kidney, and heart.

产品储存/运输

储存	Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
运输	Blue Ice

产品使用

Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 100 μg/mL and incubate the stock solution at RT for at least 20 min to ensure sufficient re-dissolved.
