P00232 Recombinant Human Fc γ

Recombinant Human Low Affinity Immunoglobulin Gamma Fc Region Receptor II-A is produced by our Mammalian expression system and the target gene encoding Ala36-Ile218(His131Arg) is expressed with a 6His tag at the C-terminus.

外观(性状)	Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.
纯度	≥95% as determined by reducing SDS-PAGE.
储存条件	Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
运输条件	The product is shipped at 2-8°C temperature. Upon receipt, store it immediately at the temperature listed below.
背景说明	Human FcγRs are divided into three classes designated FcγRI (CD64)，FcγRII (CD32)，and FcγRIII (CD16)，which generate multiple isoforms，are recognized.The activating type receptor either has or associates non-covalently with an accessory subunit that has an immunoreceptor tyrosine-based activation motif (ITAM) in its cytoplasmic domain.FcγRI binds IgG with high affinity and functions during early immune responses，whereas FcγRII and RIII are low affinity receptors that recognize IgG as aggregates surrounding multivalent antigens during late immune responses.Human CD32，also known as Low affinity immunoglobulin γ Fc region receptor II-a (IgG Fc receptor II-a)，FcγRII A or FCGR2A Protein，is expressed on cells of both myeloid and lymphoid lineages as well as on cells of non-hematopoietic origin.Associated with an ITAM-bearing adapter subunit，FcRγ，CD32a (FcγRII A) delivers an activating signal upon ligand binding，and results in the initiation of inflammatory responses including cytolysis，phagocytosis，degranulation，and cytokine production.The responses can be modulated by signals from the co-expressed inhibitory receptors such as Fcγ RII B，and the strength of the signal is dependent on the ratio of expression of the activating and inhibitory receptors.

溶剂	Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
内毒素	Less than 0.1 ng/ug(1 IEU/ug)as determined by LAL test.
