説明	MASP2 Protein, Cynomolgus, Recombinant (His) is expressed in E. coli expression system with C-His tag. The predicted molecular weight is 46.8 kDa and the accession number is A0A2K5UJY0.

Species	Cynomolgus
Expression Host	E. coli
Tag	C-His
Accession Number	A0A2K5UJY0
別名	MAP19, MASP1P1, MASP-2, sMap
Construction	Thr287-Phe686
Protein Purity	> 95% as determined by Tris-Bis PAGE
分子量	46.8 kDa (predicted). Due to autocatalytic cleavage, the protein migrates to 21-24 kDa&28-30 kDa based on Tris-Bis PAGE result.

Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris, 200 mM NaCl (pH 9.0). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
Research Background	The dysregulation of complement cascade leads to unsolicited cytokine storm, inflammation, deterioration of alveolar lining cells, culminating in acquired respiratory destructive syndrome (ARDS). Similar pathogenesis is observed with the middle east respiratory syndrome (MERS), severe acquired respiratory syndrome (SARS), and SARS-CoV-2. Activation of the lectin pathway via mannose-binding lectin associated serine protease 2 (MASP2) is witnessed under discrete viral infections including COVID-19.
