名称: 原装|Recombinant Listeria Monocytogenes Internalin
Description Internalin Listeria monocytogenes Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 374 amino acids and having a molecular mass of 42.7kDa. The Internalin is fused with an 8 amino acid His tag at C-terminus.
Source Escherichia Coli.
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation Internalin is lyophilized from a 0.2µm filtered concentrated solution in 20mM PB pH7.4 and 300mM NaCl.
Solubility It is recommended to reconstitute the lyophilized Internalin in sterile 2XPBS not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Important note: If the concentration of NaCl is less than 150mM, the protein solution becomes turbid overnight. Please always keep the concentration of NaCl more than 250mM.
