Two antipeptide antibodies were generated in chickens against sequences shared between the mouse (P24529) and human (P07101) gene products. Antibodies were affinity-purified and then mixed in equal concentrations. These antibodies have been validated with human, mouse and rat tissues.

Volume: 1000 µL

Concentration: 200 µg/mL

Clonality: Polyclonal

Host Species: Chicken

Species Reactivity:Human, Mouse, Rat

Applications: ICC, IHC, WB

Protein Name / Synonyms: Tyrosine 3-monooxygenase (EC 1.14.16.2) (Tyrosine 3-hydroxylase) (TH)

Target Description: Human TYH (EC 1.14.16.2) is a 58,523 dalton protein (528 amino acids) responsible for the enzymatic conversion of L-tyrosine to L-DOPA (dihydroxyphenylalanine). This enzyme is expressed in all catecholaminergic neurons of the CNS and PNS. In the CNS, TYH-positive neurons can be found within the substantia nigra, ventral tegmental area, locus ceruleus, and hypothalamus. In the PNS, TYH-positive neurons can be found within the sympathetic chain, pre-vertebral ganglia and the adrenal medulla.

Gene ID: TH TYH

Antibody Registry ID (RRID): AB_10013440

Physical State: Liquid

Production Notes: Chickens were immunized with two synthetic peptide / keyhole limpet hemocyanin (KLH) conjugates. These synthetic peptides corresponded to different regions of the Tyrosine Hydroxylase gene product, but were shared between the human (P07101, NCBI) and mouse (P24529, NCBI) sequences. After repeated injections into the hens, immune eggs were collected, and the IgY fractions were purified from the yolks. These IgY fractions were affinity-purified using a peptide column, and the concentrations of the eluates adjusted to 200 µg/mL. Finally, equal volumes of both affinity-purified anti-peptide antibody preparations were mixed, and the preparation was filter-sterilized.

Validation and Application Notes

Molecular Weight: 60 kDa

Western Blot Dilution Range: 1:1000-1:2000

IHC Dilution Range: 1:1000-1:2000

Quality Control

Both of the antibodies were analyzed by immunohistochemistry (at a concentration of 3 µg/mL) using fluorescein-labeled goat anti-chicken IgY (1:500 dilution, Aves Labs Cat.# F-1005) as the secondary reagent.

Storage

Store at 4°C in the dark. Under these conditions, the antibodies should have a shelf life of at least 12 months (provided they remain sterile). Do not freeze these antibodies unless you want to store them for longer periods of time. Note, however, that each time an antibody preparation is frozen, about half of its binding activity is lost.

AvesLabs是一家成立于上世纪九十年代，专注于高亲和性鸡源抗体的研发和准备，生物医药和生命科学行业全球*的鸡多克隆抗体(IgY)及定制抗体/多肽/免疫试剂的专业公司。AvesLabs在鸡源神经系统标志蛋白/抗体研究领域拥有独特优势，不仅品种多样，质量优良，而且适用于人/大小鼠等多个物种的神经系统研究，包括神经元/胶质细胞/雪旺细胞的各亚细胞结构免疫双标/免疫共沉淀研究。公司独有的技术及优质抗体产品有助于全球科研人员更为便捷的解决学术研究及应用研发课题。除了丰富的产品线外，AvesLabs还为客户提供优质的抗体定制服务，您只需要提供需要研究的重组蛋白或合成多肽，我们即可为您生产优质的鸡源多克隆抗体。

神经元标志蛋白抗体该系列产品主要用于神经元细胞的各亚细胞结构研究，可与现有的小鼠/兔抗体进行免疫双标，反应性包括人、小鼠等多个哺乳类动物。在保证抗体特异性的前提下，部分产品可分为抗不同的氨基酸片段。该系列产品包括抗APP3/APP345/APP4/APP5/ABN/TUJ/CAT/DCX/ER1/ER2/ER3/ER5/GAD/GAP43/MAP/NET/NUN/NSE/NFH/NFL/NFM/PER/PRN/PAP/STG/TAU/TYH的抗体。除单独的抗体提供，我们还可同时提供1/3种任意抗体组合及相应二抗的试剂盒，以更优惠的价格及便捷性以满足研究人员的不同需要。

胶质细胞及雪旺细胞标志蛋白抗体该系列产品主要用于胶质细胞及雪旺细胞的各亚细胞结构的研究，可与可与现有的小鼠/兔抗体进行免疫双标，反应性包括人、大鼠等多个哺乳类动物。在保证抗体特异性的前提下，部分产品可分为抗不同的氨基酸片段。该系列产品包括抗COR/GFAP/MAC/MBP/NES/PZO/PLP/VIM抗体。同样，除单独的抗体提供，我们还可同时提供1/3种任意抗体组合及相应二抗的试剂盒，以更优惠的价格及便捷性以满足研究人员的不同需要。

二抗该系列产品特点在于鸡IgY分子与哺乳动物IgG分子截然不同，因此由之制备的二抗不与来源于兔、小鼠或其他哺乳动物的一抗产生交叉反应，特别适用于组织学的免疫双标检测。该系列源于羊的二抗可交联荧光基团/HRP/生物素/琼脂糖，可广泛用于WB，免疫组化/免疫细胞化学及免疫共沉淀研究。

mmunoprecipitationReagents(IP)该系列产品中 HA-PrecipHen® 由鸡anti-HAepitopetag抗体共价结合到琼脂糖粒而成，适用于利用HAepitope-tagged蛋白的immunoprecipitation(IP),chromatinimmunoprecipitation(ChIP)以及蛋白纯化研究。而IgY-PrecipHen®由羊抗鸡的IgY抗体共价结合到琼脂糖粒上而成，适用于鸡源抗体与目标蛋白之间的immunoprecipitation(IP),chromatinimmunoprecipitation(ChIP)以及蛋白纯化研究。

对高度保守的哺乳动物基因产物有更高的描述由于鸡与哺乳动物的距离至少有1亿年之久，它们倾向于将哺乳动物的任何基因产物视为外来物，并产生强烈的免疫反应。简单双疣状鸡IgYs可以与小鼠和兔抗体一起使用，没有交叉反应的危险。针对鸡igy的二级抗体不会与哺乳动物igg发生交叉反应。友好型我们从鸡蛋中纯化抗体，而不是血清。与此相反，在兔实验中，通过抑制动物，进行耳出血或心脏穿刺来获得血清。这只是一种更人道的产生抗体的方法。成本效益和更持久的我们的鸡用抗体是>90%IgY，在4度完美呈现5年以上保质期。相比之下，多数公司提供的rabbitserum(兔乳)在4˚C (完美呈现)(以周至月为单位)的货架期非常有限，而且一旦冷冻，一些生物活性会丧失。将兔抗体纯化至相应纯度的成本。蛋白质a纯化)是非常昂贵的。几乎无限量我们从每只母鸡那里收集了大约18个“免疫鸡蛋”，但是只使用了6个“免疫鸡蛋”来准备你的IgY准备。然后我们把剩下的12个“免疫鸡蛋”储存在冰箱里，以备将来你需要更多的抗体。此外，我们可以继续为母鸡提供住宿(另收费)，以备您需要我们进行额外的注射。鸡IgY的茎部没有“Fc结构域”这提供了几个优势比兔igg:它减少了在诊断应用中出现假阳性的可能性，因为是哺乳动物的Fc域结合“类风湿因子”或其他自然产生的抗Fc抗体。不激活哺乳动物补体系统，允许鸡IgYs在体内应用。不与哺乳动物Fc受体结合，避免与表达此类受体的细胞(如巨噬细胞和树突状细胞)发生非特异性结合。
