• Product Overview: Recombinant Peptostreptococcus magnus Protein L fused with the polyhistidine tag at N-terminus and a single cysteine at C-terminus was expressed in E. coli.

Specification

• Species: Peptostreptococcus magnus
• Source: E.coli
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4.
• Bio-activity: Measured by its binding ability in a functional ELISA.Immobilized Immobilized Human IgG1 containing Kappa L chain at 5 μg/mL (100 μL/well) can bind Recombinant Protein L Protein.The EC50 is typically 0.1-1 ng/mL.
