Synonym
MAP19; MASP-2; MASP1P1; sMap
Source / expression
Recombinant Human MASP2 Protein is expressed from E.coli with His tag at the C-Terminus.It contains Gly288-Phe686 [Accession | O00187-1].
Molecular weight
The protein has a predicted MW of 46.9 kDa. Due to autocatalytic cleavage, the protein migrates to 18 kDa&25-30 kDa based on Bis-Tris PAGE result.
Endotoxin
Less than 1 EU per μg by the LAL method.
Purity
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Formulation
Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 200 mM NaCl (pH 9.0). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
Storage
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
