| Description | AP-StabilPLUS is used for the dilution and stabilization of Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enables the making of prediluted, ready-to-use AP-conjugates, minimizing assay errors inAP-StabilPLUS is used for the dilution and stabilization of Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enables the making of prediluted, ready-to-use AP-conjugates, minimizing assay errors in dilution.Stabilization of AP conjugated antibodies in low as well as high protein dilutions is seen, when using AP-StabilPLUS. When tested with AP conjugated antibody stability is seen as follows:at least 3 years at 2-8 °Cat least 2 years at room temperatureat least 4 weeks at 37 °CProduct Characteristics AP-StabilPLUS is used for the dilution and stabilization of Alkaline Phosphatase (AP) labeled proteins and antibodies, in order to maintain the molecular conformation and prevent loss of activity over time. This enables the making of prediluted, ready-to-use AP-conjugates, minimizing assay errors in dilution.When testing the AP-StabilPLUS with AP conjugated antibodies, stability is seen as follows: • at least 3 years at 2-8 °C • at least 2 years at room temperature • at least 4 weeks at 37 °C Stabilization of AP conjugated antibodies works well in low as well as in high protein dilutions.Composition & Properties AP-StabilPLUS is a ready-to use buffer that appears as an opaque solution. The product is based on a mild Tris buffer containing proprietary stabilizing components. AP-StabilPLUS contains neither BSA, nor other material from bovine serum, azide, mercury or other toxic components.Working Procedure 1.Make a series of dilutions of the AP-conjugated protein in AP-StabilPLUS in order to determine the optimal dilution. 2.Run the assay as usual or store the diluted APconjugated protein preferably at 2-8 °C.Tips & Tricks • Avoid using phosphate buffers for AP-conjugated antibody assays. We recommend the use of Tris/HCl, Tween as the washing buffer, instead of a PBS buffer which will reduce signal significantly.Handling & Storage • Store solution at 2-8 °C...

The human CD200 R1 cDNA encodes a 325 Purity:>95%, by SDS-PAGE visualized with Coomassie® Blue Staining.Description：CD200 R1, also known as OX-2 receptor, is a 90 kDa transmembrane protein in the immunoglobulin superfamily and is important in the regulation of myeloid cell activity. The human CD200 R1 cDNA encodes a 325 amino acid (aa) precursor that includes a 28 aa signal sequence, a 215 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 61 aa cytoplasmic domain. The ECD is composed of one Ig-like V-type domain and one Ig-like C2-type domain. Within the ECD, human CD200 R1 shares 56% aa sequence identity with both mouse and rat CD200 R1. Alternate splicing of the human CD200 R1 mRNA generates four isoforms, two of which are truncated in the Ig-C2 domain and are likely secreted. In human, a separate CD200 RL gene encodes a protein that shares 81% ECD aa identity with CD200 R1. In mouse, at least four genes for CD200 R1-like molecules have been described. CD200 R1 expression is restricted primarily to mast cells, basophils, macrophages, and dendritic cells, while its ligand, CD200, is widely distributed. Disruption of this receptor-ligand system by knockout of the CD200 gene in mice leads to increased macrophage number and activation and predisposition to autoimmune disorders. Association of CD200 with CD200 R1 takes place between their respective N-terminal Ig-like domains. The capacity of CD200 R1-like molecules to interact with CD200 is controversial. CD200 R1 propagates inhibitory signals despite lacking a cytoplasmic ITIM (immunoreceptor tyrosine-based inhibitory motif). CD200 R1-like molecules, in contrast, are potentially activating receptors by means of their association with DAP12. CD200R1 signaling inhibits the expression of proinflammatory molecules including TNFs, IFNs, and inducible nitric oxide synthase in response to selected stimuli, which implicate that CD200/CD200R1 inhibitory signaling pathway plays a prominent role in limiting inflammation in a wide range of inflammatory diseases. Furthermore, the CD200/CD200R inhibitory signaling constitutes one of the most suitable endogenous immunoregulatory molecule candidate to restore the immune suppressive status of the CNS altered in chronic neuroinflammatory situations...
