通用注释
亚单元:
Homodimer. Interacts with ALK. Interacts with LRP1; promotes neuronal survival. Interacts with LRP2. Interacts with NCAM1 (By similarity). Interacts (via C-terminal) with PTPRZ1 (via chondroitin sulfate chains); this interaction is inhibited by PTN; this interaction promotes neuronal migration (PubMed:10212223). Interacts with NCL; this interaction promotes NCL clustering and lateral movements of this complex into lipid rafts leading to MDK internalization. Interacts with LRP6 and LRP8: this interaction is calcium dependent. Interacts with ITGA4. Interacts with ITGA6. Interacts with ITGB1. Interacts with ITGA4:ITGB1 complex; this interaction mediates MDK-induced osteoblast cells migration through PXN phosphorylation. Interacts with ITGA6:ITGB1 complex; this interaction mediates MDK-induced neurite outgrowth. Interacts with NOTCH2; this interactio mediates a nuclear accumulation of NOTCH2 and therefore activation of NOTCH2 signaling leading to interaction between HES1 and STAT3. Interacts with GPC2 (via heparan sulfate chain); this interaction is inhibited by heparin followed by chondroitin sulfate E; this interaction induces GPC2 clustering through heparan sulfate chain; this interaction induces neuronal cell adhesion and neurite outgrowth (By similarity). Interacts with SDC3; this interaction induces SDC3 clustering; this interaction induces neuronal cell adhesion and neurite outgrowth (PubMed:9089390, PubMed:12084985). Interacts with SDC1 (PubMed:9089390). Interacts with CSPG5; this interaction promotes elongation of oligodendroglial precursor-like cells (PubMed:16901907).
功能:
Secreted protein that functions as cytokine and growth factor and mediates its signal through cell-surface proteoglycan and non-proteoglycan receptors (PubMed:16901907). Binds cell-surface proteoglycan receptors via their chondroitin sulfate (CS) groups (PubMed:17230638). Thereby regulates many processes like inflammatory response, cell proliferation, cell adhesion, cell growth, cell survival, tissue regeneration, cell differentiation and cell migration (PubMed:17230638, PubMed:19060126, PubMed:17015789, PubMed:28183532, PubMed:10683378, PubMed:15482347, PubMed:15509530, PubMed:24458438, PubMed:25551381, PubMed:29233575). Participates in inflammatory processes by exerting two different activities. Firstly, mediates neutrophils and macrophages recruitment to the sites of inflammation both by direct action by cooperating namely with ITGB2 via LRP1 and by inducing chemokine expression (PubMed:10683378, PubMed:15509530, PubMed:24458438, PubMed:28183532). This inflammation can be accompanied by epithelial cell survival and smooth muscle cell migration after renal and vessel damage, respectively (PubMed:15509530, PubMed:10683378). Secondly, suppresses the development of tolerogenic dendric cells thereby inhibiting the differentiation of regulatory T cells and also promote T cell expansion through NFAT signaling and Th1 cell differentiation (PubMed:28183532). Promotes tissue regeneration after injury or trauma. After heart damage negatively regulates the recruitment of inflammatory cells and mediates cell survival through activation of anti-apoptotic signaling pathways via MAPKs and AKT pathways through the activation of angiogenesis (PubMed:17015789, PubMed:19060126). Also facilitates liver regeneration as well as bone repair by recruiting macrophage at trauma site and by promoting cartilage development by facilitating chondrocyte differentiation (PubMed:15482347, PubMed:25551381). Plays a role in brain by promoting neural precursor cells survival and growth through interaction with heparan sulfate proteoglycans (PubMed:17230638). Binds PTPRZ1 and promotes neuronal migration and embryonic neurons survival (By similarity). Binds SDC3 or GPC2 and mediates neurite outgrowth and cell adhesion (By similarity). Binds chondroitin sulfate E and heparin leading to inhibition of neuronal cell adhesion induced by binding with GPC2 (PubMed:10978312). Binds CSPG5 and promotes elongation of oligodendroglial precursor-like cells (PubMed:16901907). Also binds ITGA6:ITGB1 complex; this interaction mediates MDK-induced neurite outgrowth (By similarity). Binds LRP1; promotes neuronal survival (By similarity). Binds ITGA4:ITGB1 complex; this interaction mediates MDK-induced osteoblast cells migration through PXN phosphorylation (By similarity). Binds anaplastic lymphoma kinase (ALK) which induces ALK activation and subsequent phosphorylation of the insulin receptor substrate (IRS1), followed by the activation of mitogen-activated protein kinase (MAPK) and PI3-kinase, and the induction of cell proliferation (By similarity). Promotes epithelial to mesenchymal transition through interaction with NOTCH2 (By similarity). During arteriogenesis, plays a role in vascular endothelial cell proliferation by inducing VEGFA expression and release which in turn induces nitric oxide synthase expression. Moreover activates vasodilation through nitric oxide synthase activation (PubMed:29233575). Negatively regulates bone formation in response to mechanical load by inhibiting Wnt/beta-catenin signaling in osteoblasts (PubMed:21185956, PubMed:20200993). In addition plays a role in hippocampal development, working memory, auditory response, early fetal adrenal gland development and the female reproductive system (PubMed:16619002, PubMed:17121547, PubMed:10096022).

小鼠肝素结合细胞因子(Mdk)ELISA试剂盒原理？
双抗体夹心法：用纯化的抗体包被微孔板，制成固相抗体，往包被有固相抗体的微孔中依次加入标准品或受检样本、生物素化抗体、HRP标记的亲和素，经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值）,计算样本浓度。
竞争法：用纯化的抗体包被微孔板，制成固相抗体，往包被有固相抗体的微孔中依次加入标准品或受检样本和生物素标记的目标分析物，受检标本中抗原与生物素标记抗原竞争结合有限的抗体。再加入HRP标记的亲和素，经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值）,计算样本浓度。

如何分析小鼠肝素结合细胞因子(Mdk)ELISA试剂盒数据？
建议标准曲线，并计算样本浓度。对于elisa的曲线拟合，一般建议采用4参数曲线拟合，4参数曲线拟合通常更适合免疫分析。推荐使用专业软件进行曲线拟合，例如curve expert 1.3。根据样本的OD值由标曲查出相应的浓度，再乘以稀释倍数；或用标准物的浓度与OD值计算出标曲的回归方程式，将样本的OD值代入方程式，计算出样本浓度，再乘以稀释倍数，即为样本的实际浓度。以下链接是curve expert 1.3软件拟合曲线的方法。
