Details
Description:Mouse monoclonal antibody against Thr181 phosphorylated Tau protein
Purification:Protein G affinity purified
Product Type: Primary antibody
Target Protein:Human Thr181 phosphorylated Tau
Immunogen:KLH conjugated with a short peptide [Ala-Pro-Lys-Thr(p)-Pro-Pro-Ser-Ser-Gly-Glu-Cys], corresponding to the amino acid sequence 177-187 on the phosphorylated Tau protein.
Fusion Myeloma:Sp2/0-Ag14
Specificity:This antibody reacts with the unconjugated Thr181 phosphorylated Tau peptide.
Species Reacitvity:Human, mouse
Host / Isotype: Mouse, IgG2a Kappa
Formulation:Lyophilized from a solution in 0.01M PBS pH7.2
Reconstitution:Double distilled water is recommended to adjust the final concentration to 1.00mg/mL. Avoid repeated freeze and thaw cycle.
Storage: Store at -20oC
Research Area:Alzheimer’s disease and other neurodegenerative diseases
Background:
Tau is a highly soluble microtubule associated protein found in high concentration in neuron of central nervous system. The main function of the protein is stabilizing the microtubule in nerve fibre (axon). There are six tau isoforms which are formed by alternate splicing. Hyperphosphorylation of Tau protein results in aggregation and formation of neurofibrillary tangles, which is significantly associated with cognitive impairment in Alzheimer’s disease. Tau Thr181 phosphorylation has been used as a biomarker for the differentiation of Alzheimer’s disease and other primary dementia such as dementia with Lewy bodies..
Application:
1. Indirect ELISA: The antibody reacts with phosphorylated peptide [Ala-Pro-Lys-Thr(p)-Pro-Pro-Ser-Ser-Gly-Glu-Cys] coated ELISA plate in indirect ELISA. Cross-reactivity with un-phosphorylated peptide is very low.
2. Western Blot:The antibody detected a 46kD band in mouse brain tissue lysate.
Detect the mouse brain tissue lysates using antibody (Tau-pho181 1A4) at 1:2000 (0.5 μg/mL) dilution.

第一代热启动Taq酶是一种DNA聚合酶。 第一代指的是直接从Taq（这是一种细菌）体内提取的天然聚合酶，没有进行化学修饰的，为了达到更好的聚合催化效果，往往需要经过酶工程处理，得到的聚合酶催化效率更高。 热启动是指这种酶的反应温度条件
Taq DNA polymerase是从克隆有Thermu aquaticus DNA Polymerase基因的大肠杆菌经诱导表达后，再经过柱纯化分离出来的一个约94 KD的重组蛋白。无外源核酸酶和细菌DNA污染，稳定性好，特异性强，适用于常规PCR扩增。

针对DDX家族成员在RNA识别和代谢及其在调控抗病毒天然免疫应答中发挥的重要功能，通过筛选多种DDX家族成员在病毒感染巨噬细胞天然免疫应答中的作用，发现了DDX46能显著抑制病毒感染诱导的干扰素表达
DDX46能结合到抗病毒效应分子mRNA的CCGGUU保守基序上，当病毒感染时DDX46与m6A去甲基化酶ALKBH5结合增加，使得与DDX46结合的抗病毒效应分子mRNA发生去甲基化修饰而导致其核滞留，阻滞了这些抗病毒效应分子的蛋白表达从而降低干扰素产生，最终抑制了抗病毒天然免疫应答反应

核酶（ribozyme）是指一类具有催化功能的RNA分子，通过催化靶位点RNA链中磷酸二酯键的断裂，特异性地剪切底物RNA分子，从而阻断基因的表达.
核酶的催化功能与其空间结构有密切关系，目前已知有多种特殊结构的核酶：
RNaseP的RNA碱基（M1 RNA）、锤头型、发夹型丁型肝炎病毒RNA、1类内含子和2类内含子，大多有hammerhead structure。
不同的核酶可分为两类：
1 剪切型核酶：只剪不接，如M1 RNA
2 剪接型核酶：该酶具有序列特异的内切核酸酶、RNA连接酶等多种酶活性，如1类和2类内含子向左转|向右转
