Yes
Specifications
Target
IL-4
Synonyms
IL4 ; IL-4 ; interleukin 4 ; MGC79402 ; pitrakinra ; B cell growth factor 1 ; BCDF ; BCGF1 ; BCGF-1 ; binetrakin ; BSF1 ; BSF-1 ; BSF-1
Accession
Species
Human
Exact Sequence
His25-Ser153
Molecular Weight
The protein has a predicted MW of 17.8 kDa. Due to glycosylation, the protein migrates to 23-25 kDa based on Tris-Bis PAGE result.
Activity
Immobilized Human IL-4 R alpha, hFc Tag at 0.5ug/ml (100ul/Well) on the plate. Dose response curve for Biotinylated Human IL-4, His Tag with the EC50 of 5.0ng/ml determined by ELISA. See testing image for detail.
Product Tag
C-His-Avi
Express System
HEK293
Purity
> 95% as determined by Tris-Bis PAGE
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 8% 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.
