Il1r1-5651M
Optional Service: Optional requirements on this protein
Product Overview :
RecombinantMouse Il1r1 protein was expressed in Spodopterafrugiperdawith the Fc part of Human IgG1 Pro100-Lys330 (C-terminus) and MouseIl1r1 Phe14-Glu355 (N-terminus).
Description :
Twodistinct types of receptors that bind the pleiotropic cytokines IL-1α andIL-1β have been described. The Il1r1 is an 80 kDa transmembrane protein thatis expressed predominantly by T cells, fibroblasts, and endothelialcells. IL-1receptor type II is a 68 kDa transmembrane protein found on B lymphocytes, neutrophils,monocytes, large granular leukocytes and endothelial cells. Both receptorsare members of the immunoglobulin superfamily and show approximately 28% sequencesimilarity in their extracellular domains. The two receptor types do not heterodimerizein a receptor complex.
Source :
Spodopterafrugiperda, Sf 21 (baculovirus)-derived.
Form :
Lyophilizedfrom a 0.2 um filtered solution in PBS.
N-terminalSequence :
Phe14
MolecularWeight :
64.7 kDa (monomer)
Activity :
Measuredby its ability to inhibit IL-1α-dependent proliferation in D10.G4.1 mousehelper T cells. Approximately 2-8 μg/mL of IL-1 RII will inhibit 50% of thebiological response due to 50 pg/mL of recombinant mouse IL-1α.
Endotoxin Level :
<1.0EU per 1μg of the protein by the LAL method.
SDS-PAGE :
70-80kDa, reducing conditions.
Purity :
>95%,by SDS-PAGE under reducing conditions and visualized by silver stain.
Reconstitution :
500 μg/mLin sterile PBS
Storage :
Use amanual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70°C as supplied.1 month, 2 to 8°C under sterile conditions after reconstitution. 3months, -20 to -70°C under sterile conditions after reconstitution.
