亚单元:
(Microbial infection) Interacts with M.tuberculosis EsxA (PubMed:20800577). Interacts with M.bovis MPB83 (PubMed:20800577).
功能:
Cooperates with LY96 to mediate the innate immune response to bacterial lipoproteins and other microbial cell wall components. Cooperates with TLR1 or TLR6 to mediate the innate immune response to bacterial lipoproteins or lipopeptides (PubMed:21078852, PubMed:17889651). Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. May also activate immune cells and promote apoptosis in response to the lipid moiety of lipoproteins (PubMed:10426995, PubMed:10426996). Recognizes mycoplasmal macrophage-activating lipopeptide-2kD (MALP-2), soluble tuberculosis factor (STF), phenol-soluble modulin (PSM) and B.burgdorferi outer surface protein A lipoprotein (OspA-L) cooperatively with TLR6 (PubMed:11441107). Stimulation of monocytes in vitro with M.tuberculosis PstS1 induces p38 MAPK and ERK1/2 activation primarily via this receptor, but also partially via TLR4 (PubMed:16622205). MAPK activation in response to bacterial peptidoglycan also occurs via this receptor (PubMed:16622205). Acts as a receptor for M.tuberculosis lipoproteins LprA, LprG, LpqH and PstS1, some lipoproteins are dependent on other coreceptors (TLR1, CD14 and/or CD36); the lipoproteins act as agonists to modulate antigen presenting cell functions in response to the pathogen (PubMed:19362712). M.tuberculosis HSP70 (dnaK) but not HSP65 (groEL-2) acts via this protein to stimulate NF-kappa-B expression (PubMed:15809303). Recognizes M.tuberculosis major T-antigen EsxA (ESAT-6) which inhibits downstream MYD88-dependent signaling (shown in mouse) (By similarity). Forms activation clusters composed of several receptors depending on the ligand, these clusters trigger signaling from the cell surface and subsequently are targeted to the Golgi in a lipid-raft dependent pathway. Forms the cluster TLR2:TLR6:CD14:CD36 in response to diacylated lipopeptides and TLR2:TLR1:CD14 in response to triacylated lipopeptides (PubMed:16880211). Required for normal uptake of M.tuberculosis, a process that is inhibited by M.tuberculosis LppM.

Single-pass type I membrane protein
Membrane raft
Does not reside in lipid rafts before stimulation but accumulates increasingly in the raft upon the presence of the microbial ligand. In response to diacylated lipoproteins, TLR2:TLR6 heterodimers are recruited in lipid rafts, this recruitment determines the intracellular targeting to the Golgi apparatus. Triacylated lipoproteins induce the same mechanism for TLR2:TLR1 heterodimers.

人Toll样受体2(TLR2)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。

人Toll样受体2(TLR2)ELISA试剂盒中需要使用的样品量是多少？
夹心法100μL/孔，竞争法50μL/孔。如样本浓度过高时，应对样本进行稀释，以使稀释后的样本符合试剂盒的检测范围，计算时再乘以相应的稀释倍数。
[6].
如何分析人Toll样受体2(TLR2)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。

人Toll样受体2(TLR2)ELISA试剂盒中是否包含人和动物的副产物，是否包含感染的或者传染性原料如HIV等？
除了抗体和稀释液中的BSA，不含其它人和动物的副产物，也不含感染材料。

收集人Toll样受体2(TLR2)ELISA试剂盒血浆样本，用什么作为抗凝剂？
一般建议用EDTA和肝素作为抗凝剂。

人Toll样受体2(TLR2)ELISA试剂盒酶标板可以拆成几部分？拆的时候是否需要避光，无菌？
人Toll样受体2(TLR2)ELISA试剂盒酶标板是8×12孔条，可拆卸，板子可以拆成12条，注意避免孔污染，不需要避光和无菌。暂时不用的板子，放回原来装的袋子里，密封保存。

TLR-2 is membrane protein receptor which sits on the surface of certain cells
I have bought your product (TLR-2 ELISA kit). In your introduction, you
told us that TLR-2 is membrane protein receptor which sits on the surface
of certain cells.
My questions are:
1. Can we detect the TLR-2 from culture supernatant, while the TLR-2 sits
on the surface of cells.
2. Can we detect TLR-2 from blood serum, if so, where does TLR-2 come from
while TLR-2 sits on the surface of cells?
