Recombinant Human Fc Receptor-Like B, His-tagged

Cat. No.: FCRLB-512H
Product Overview: RecombinantHuman FCRLB protein was expressed in Murine myeloma cellline. Ala18-Ser426,with a C-terminal 6-His tag.
Description: FCRLB isa 60 kDa protein with sequence homology to classical Fc receptors. There areat least six type 1 transmembrane FCRL proteins and two that lack transmembranesegments. Each family member contains between three and nine immunoglobulin-likedomains. FCRL proteins are differentially expressed within the B cell lineageand can either promote or inhibit B cell proliferation and activation. Accordingto R&D Systems testing, FCRLB binds to purified human IgG with highaffinity. Human FCRLB shares 82% and 85% amino acid sequence identity withmouse and rat FCRLB, respectively. It contains a putative signal peptide,three immunoglobulin-like domains, and a mucinlike stalk that is rich in Pro,Ser, and Thr residues.
Source: Murine myeloma cellline, NS0-derived.
Form: Lyophilized from a0.2 um filtered solution in PBS and EDTA.
N-terminalSequence: Ala18
MolecularWeight: 46 kDa
Activity: Measuredby its ability to bind human IgG with an estimated KD < 120 nM.
Endotoxin Level: <1.0EU per 1μg of the protein by the LAL method.
SDS-PAGE: 65-70kDa, reducing conditions.
Purity: >90%,by SDS-PAGE under reducing conditions and visualized by silver stain.
Reconstitution: Reconstitute at 100μg/mLin PBS.
Storage: Use amanual defrost freezer and avoid repeated freezethaw 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.
