Name :
IgG1 Fc Protein
Description :
Recombinant murine Fc fragment contains the hinge region, CH2, and CH3 region of the mouse IgG1 isotype. IgG1 is most abundant in serum among the four IgG subclasses (IgG1, 2, 3 and 4) and binds to Fc receptors (FcγR) on phagocytic cells with high affinity. Fc fragment is demonstrated to mediate phagocytosis, trigger inflammation, and target Ig to particular tissues.
Species :
Mouse
Uniprotkb :
HEK293
Tag :
No Tag
Synonyms :
VH7183, RGD1359539, IgG1, Igh-4
Construction :
Recombinant Mouse IgG1 Fc Protein is expressed from HEK293 without tag. It contains Val98-Lys324.[Accession |P01868]
Protein Purity :
> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight :
The protein has a predicted MW of 25.7 kDa. Due to glycosylation, the protein migrates to 30-40 kDa based on Tris-Bis PAGE result.
Endotoxin :
Less than 1EU per μg by the LAL method.
Formulatione :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability & Storage :
-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Shipping :
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
