The affinity constant of 17.61 nM as determined in SPR assay (Biacore T200). See testing image for detail.
Product Tag
C-His-Avi
Express System
HEK293
Purity
> 95% as determined by Tris-Bis PAGE;> 95% as determined by SEC-HPLC
Endotoxin
Less than 1EU per ug by the LAL method.
Shipping, Reconstitution & Storage
Appearance
Lyophilized
Shipping Conditions
Shipped at ambient temperature.
Formulation
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
Reconstitution
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability & Storage
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
