Other Tags and Version Biotin & Other Labeled Version
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 69.8 kDa. The protein migrates as 80-90 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in 20 mM HEPES,150 mM NaCl,pH7.5 with trehalose as protectant.

Performance Data
SDS-PAGE
Rhesus macaque Coagulation factor XI Protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).
Bioactivity-ELISA
Immobilized Rhesus macaque Coagulation factor XI Protein, His Tag (Cat. No. FXI-C52H3) at 1 μg/mL (100 μL/well) can bind Abelacimab with a linear range of 0.03-2 ng/mL (QC tested).
Protocol
Immobilized Abelacimab at 1 μg/mL (100 μL/well) can bind Rhesus macaque Coagulation factor XI Protein, His Tag (Cat. No. FXI-C52H3) with a linear range of 0.001-0.063 μg/mL (Routinely tested).
Protocol
Bioactivity-SPR
Abelacimab captured on Protein A Chip can bind Rhesus macaque Coagulation factor XI, His Tag (Cat. No. FXI-C52H3) with an affinity constant of 22.4 pM as determined in a SPR assay (Biacore 8K) (Routinely tested).
Protocol
Bioactivity
Measured by its ability to cleave the fluorogenic peptide substrate, t-butyloxycarbonyl-Ile-Glu-Gly-Arg-7-amido-4-methylcoumarin (Boc-IEGR-AMC). The specific activity is >110 pmol/min/µg (QC tested).
