Recombinant Mouse LEPR Protein (Leu22-Gly839), C-mFc-tagged
Product Description
Cat
IMP-9896
Official Symbol
Lepr
Product Overview
Recombinant Mouse Leptin R protein (Leu22-Gly839) with a Mouse IgG2A (Glu98-Lys330) Fc tag at C-terminus was expressed in Mouse myeloma cell line.
Description
The protein encoded by this gene belongs to the gp130 family of cytokine receptors that are known to stimulate gene transcription via activation of cytosolic STAT proteins. This protein is a receptor for leptin (an adipocyte-specific hormone that regulates body weight), and is involved in the regulation of fat metabolism, as well as in a novel hematopoietic pathway that is required for normal lymphopoiesis. Mutations in this gene have been associated with obesity and pituitary dysfunction. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. It is noteworthy that this gene and LEPROT gene (GeneID:54741) share the same promoter and the first 2 exons, however, encode distinct proteins (PMID:9207021).
Expression System
Mouse myeloma cell line
Species
Mouse
Tag
C-mFc
Predicted N Terminal
Leu22
Form
Lyophilized from a 0.2 μm filtered solution in MES and NaCl.
Molecular Mass
Predicted Molecular Mass: 119.6 kDa (monomer)
SDS-PAGE: 125-190 kDa, reducing conditions
Protein length
Leu22-Gly839
Bio-activity
Measured by its ability to inhibit Leptin-dependent proliferation of BaF3 mouse pro-B cells transfected with human Leptin R. The ED50 for this effect is 2-10 ng/mL in the presence of 1 ng/mL recombinant mouse Leptin.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>90%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Notes
Disulfide-linked homodimer
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution
