产品介绍 The Toll-like receptor (TLR) family in mammals comprises a family of transmembrane proteins characterized by multiple copies of leucine rich repeats in the extracellular domain and IL-1 receptor motif in the cytoplasmic domain. Like its counterparts in Drosophila, TLRs signal through adaptor molecules. The TLR family is a phylogenetically conserved mediator of innate immunity that is essential for microbial recognition. Ten human homologs of TLRs (TLR1-10) have been described. TIRAP (TIR domain-containing adaptor protein) is an adaptor protein used by TLR4. Blocking TIRAP inhibits TLR4-mediated signaling events, including DC maturation and cytokine production.
Function : Adapter involved in TLR2 and TLR4 signaling pathways in the innate immune response. Acts via IRAK2 and TRAF-6, leading to the activation of NF-kappa-B, MAPK1, MAPK3 and JNK, and resulting in cytokine secretion and the inflammatory response. Positively regulates the production of TNF-alpha and interleukin-6.
Subunit : Homodimer. Also forms heterodimers with MyD88. Binds to TLR4 and IRAK2 via their respective TIR domains. Binds to BMX, PKR and TBK1. Does not interact with IRAK1, nor TLR9.
Subcellular Location : Cytoplasm.
Tissue Specificity : Highly expressed in liver, kidney, spleen, skeletal muscle and heart. Also detected in peripheral blood leukocytes, lung, placenta, small intestine, thymus, colon and brain.
Post-translational modifications : Phosphorylated by IRAK1 and IRAK4. Also phosphorylated by BTK.
Polyubiquitinated. Polyubiquitination follows phosphorylation by BTK and leads to TIRAP degradation.
Similarity : Contains 1 TIR domain.

抗体的生物素化标记实验要点:
1. 磷酸化白细胞介素1受体衔接蛋白抗体费用 如在反应混合液中有叠氮钠或游离氨基存在,会抑制标记反应。因此,蛋白质在反应前要对 0.1mol/L碳酸氢钠缓冲液或0.5mol/L硼酸缓冲液充分透析;
2.所用的NHSB及待生物素化蛋白质之间的分子比按蛋白质表面的ε-氨基的密度会有所不同,选择不当则影响标记的效率,应先用几个不同的分子比来筛选最适条件;
3.用NHSB量过量也是不利的,抗原的结合位点可能因此被封闭,导致抗体失活;
4.由于抗体的氨基不易接近可能造成生物素化不足,此时可加入去污剂如 Triton x-100, Tween20等;
5.当游离ε-氨基(赖氨酸残基的氨基)存在于抗体的抗原结合位点时,或位于酶的催化位点时,生物素化会降低或损伤抗体蛋白的结合力或活性;
6.生物素还可能与不同的功能基团,如羰基、氨基、巯基、异咪唑基及苯酚基,也可与糖基共价结合;
7.交联反应后,应充分透析,否则,残余的生物素会对生物素化抗体与亲和素的结合产生竞争作用;
8.在细胞的荧光标记实验中,中和亲和素的本底低,但由于链霉亲和素含有少量正电荷,故对某些细胞可导致高本底。
抗体的鉴定:
1)磷酸化白细胞介素1受体衔接蛋白抗体费用 抗体的效价鉴定:不管是用于诊断还是用于,制备抗体的目的都是要求较高效价。不同的抗原制备的抗体,要求的效价不一。鉴定效价的方法很多,包括有试管凝集反应,琼脂扩散试验,酶联免疫吸附试验等。常用的抗原所制备的抗体一般都有约成的鉴定效价的方法,以资比较。如制备抗抗体的效价,一般就采用琼脂扩散试验来鉴定。
2)抗体的特异性鉴定:抗体的特异性是指与相应抗原或近似抗原物质的识别能力。抗体的特异性高,它的识别能力就强。衡量特异性通常以交叉反应率来表示。交叉反应率可用竞争抑制试验测定。以不同浓度抗原和近似抗原分别做竞争抑制曲线,计算各自的结合率,求出各自在IC50时的浓度,并按公式计算交叉反应率。
如果所用抗原浓度IC50浓度为pg/管,而一些近似抗原物质的IC50浓度几乎是无穷大时,表示这一抗血清与其他抗原物质的交叉反应率近似为0,即该血清的特异性较好。
3)抗体亲和力:是指抗体和抗原结合的牢固程度。亲和力的高低是由抗原分子的大小,抗体分子的结合位点与抗原决定簇之间立体构型的合适度决定的。有助于维持抗原抗体复合物稳定的分子间力有氢键,疏水键,侧链相反电荷基因的库仑力,范德华力和空间斥力。亲和力常以亲和常数K表示,K的单位是L/mol。抗体亲和力的测定对抗体的筛选,确定抗体的用途,验证抗体的均一性等均有重要意义。
