Tag Info
The following tags are available.
N-terminal His-tagged
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Component of the viral envelope that plays a central role in virus morphogenesis and assembly via its interactions with other viral proteins.
Gene References into Functions
  1. Specific amino acids are critical for M protein function in terms of directing virus assembly. PMID: 23700447
  2. Like S, M acquires high-mannose N-glycans that are subsequently modified into complex N-glycans in the Golgi. PMID: 15831954
  3. This is the first report describing the induction of apoptosis by SARS-CoV M protein in animal cells and possible implications are discussed. PMID: 16797548
  4. The results show that M and N proteins of SARS-CoV can induce apoptosis of human pulmonary fibroblast cells. PMID: 16845612
  5. The crystal structure of M(pro) at a resolution of 1.82 Angstroms, in space group P2(1) at pH 6.0, is reported. PMID: 17196984
  6. cytoplasmic C-terminus domain of SARS-CoV M protein was responsible for binding to NC protein PMID: 18792806
  7. the expression of M protein prevents the formation of TRAF3.TANK.TBK1/IKKepsilon complex and thereby inhibits TBK1/IKKepsilon-dependent activation of IRF3/IRF7 transcription factors PMID: 19380580
