The ImmunoStar 5-HT5A Receptor was quality control tested using standard immunohisto-chemical methods. The antiserum demonstrates strongly positive labeling of rat cortex and hippocampus using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilution is 1/200 - 1/400 in PBS/0.3% Triton X-100 - Bn/Av-HRP. Intensification methods such as nickel will approximately double the dilution factor as recommended. The antibody was characterized by immunoblotting and immunohistochemistry. Immunoblots of rat brain extracts revealed the presence of two bands at molecular weights of 41 and 47 kD. The lower weight band agrees with the calculated molecular weight based on amino acid sequence. The higher weight may represent glycosylated receptor protein. Immunohistochemical staining of rat brain correlates well with Northern blot analysis and in situ hybridization studies. Immunolabeling is completely abolished by preadsorption with synthetic rat 5-HT5A receptor (17-34). BlastP database sequence homology searches indicate that the amino acid sequence is unique to rat and mouse 5-HT5A receptor.Photo Description: IHC image of neurons staining for the 5-HT5A receptor in the rat hippocampus (above) and the rat cortex (below). The tissue was fixed with 4% formaldehyde/0.05% glutaraldehyde in 0.1 M phosphate buffer, before being removed and prepared for vibratome sectioning. Floating sections were incubated at RT in 10% goat serum in PBS, before standard IHC procedure. Primary antibody was incubated at 1:500 for 48 hours, goat anti-rabbit secondary was subsequently added for 1 hour after washing with PBS. Light microscopy staining was achieved with standard biotin-streptavidin/HRP procedure and DAB chromogen.

虽然没有具体用过检测这个抗原的抗体，但是如果希望抗体特异性好点，能检测丰度低的蛋白，还是选Abcam吧，Santa有时候全凭人品了，内参抗体什么的还能凑活，其他的比较勉强。
GAPDH
万能内参
主要看你的目标蛋白的分子量多大，“目标蛋白要与内参蛋白的分子量差异大！”
方便检测
核蛋白，有很多种，分子量不同
膜蛋白，有很多很多种，分子量不同
浆蛋白，有成千上万种，分子量不同。
具体实验，具体目的蛋白，具体的内参。
因为内参有好几种，分子量差别也比较大，更换分子量与检测蛋白差距更大的内参就可以避免这个问题
另外也可以先用一抗孵育显色和检测，再用Strip缓冲液洗掉膜上的抗体，重新进行内参的抗体孵育显色检测。这样也可以将检测蛋白和内参显色在同一张膜上
内参抗体：
Beta-Actin mAb (1C7) 细胞总蛋白 42 kD Abbkine A01010 小鼠源单克隆
Beta-Actin mAb (1C7) , HRP 细胞总蛋白 42 kD Abbkine A01015 小鼠源单克隆,HRP偶联
GAPDH mAb (2B5) 细胞总蛋白 36 kD Abbkine A01020 小鼠源单克隆

【GAPDH】或G3PDH是甘油醛-3-磷酸脱氢酶（ glyceraldehyde-3-phosphate dehydrogenase ）的英文缩写。GAPDH是参与糖酵解的一种关键酶，由4个30-40kDa的亚基组成，分子量146kDa，检测条带大约在36kDa。GAPDH基因几乎在所有组织中都高水平表达，且GAPDH 作为管家基因在同种细胞或者组织中的蛋白质表达量一般是恒定的。
【Western Blot】蛋白质印迹法（免疫印迹试验）。它是分子生物学、生物化学和免疫遗传学中常用的一种实验方法。其基本原理是通过特异性抗体对凝胶电泳处理过的细胞或生物组织样品进行着色。通过分析着色的位置和着色深度获得特定蛋白质在所分析的细胞或组织中表达情况的信息。
β-Actin作为内参是得到了公认的，这是针对大多数组织和细胞来说的，它广泛分布于细胞浆内，表达量非常丰富。Beta-actin由375个氨基酸组成，分子量大小为42-43kDa左右。
β-actin的蛋白水平通常不会发生改变，因此被广泛用于Western时上样量是否一致的参照，也常被用于免疫染色观察细胞的微丝结构。在用作Western的参照时，Actin抗体和Tubulin抗体的主要不同之处在于两者所识别蛋白的分子量不同，这样可以选择合适的参照在同一块胶同一张膜上实现同时检测目标蛋白和参照蛋白。向左转|向右转
