Chicken IgG Antibody, HRP
|
Product Description | Affinity purified anti-chicken Ig antibody is conjugated to periodate-oxidized-HRP. The conjugate is useful for detection, identification, quantization and localization of chicken antibodies including the chicken egg yolk antibodies. |
Species | Goat |
Formulation | 1 mg/mL in stabilizing buffer with 50% glycerol |
Immunogen | Affinity purified chicken immunoglobulins |
Purification | The antibody was affinity purified with chicken immunoglobulin on agarose followed by absorption with human gamma globulins and HSA. |
Specificity | The antibody recognizes chicken IgG (IgY). |
Conjugation | Reductive amination with periodate-activated HRP; HRP / Anti-Chicken IgG ration - 2:1 |
Applications | ELISA (1:50,000), WB (1:10,000) |
Scientific Description | IgG is a monomeric immunoglobulin. It is composed of two heavy chains (γ) and two light chains. Each IgG has two antigen binding sites that bind with many pathogens including viruses, bacteria, and fungi. It also assists in phagocytosis and the neutralization of bacterial toxins. |
Storage & Stability | Product is stable for several weeks at 4°C. For extended storage, store product at –20ºC. Expiration date is six months from date of shipping if properly stored. |

的抗体不容易染色,哪为同仁有这方面的经验?另外基因公司卖的cellsignalingtechnology的抗体要1875元,而中山公司卖的这个抗体只有800多,其中差距在哪里?请赐教
本人对软骨石蜡切片做了MMP-13的免疫组化染色,首次做,无法判断染色部位,请各位帮忙看一下
Bone Mesenchymal Stem Cells 作为一个细胞群体,还没有发现有特定细胞表面marker. 对于那些可以代表自我更新和分化的marker, 也不清楚到底要发现哪一个的表达才能确定该细胞就是BMSC。
目前常用的方法,就是采用培养,colony-forming unit-fibroblasts (CFU-F)这个方法。一般BMSC可以24-48小时贴壁。
流式细胞计数,比如STRO-1,但是一般认为STRO-1阳性的细胞更趋向于造血干细胞,和BMSC简单区别还不是很清楚。
这里有个培养分化的产品

下面的这段话是图注,图注的意思我明白,但是我想知道merge后的图看什么颜色的荧光,蓝色是细胞核,红色是lysosome(位于胞质),绿色是AMPKβ2,该实验是想观察AMPKβ2是否转位到lysosome上了,如果确实发生了AMPKβ2转位到lysosome上,那么merge后是红色与绿色融合在一起,是吗?融合在一起发什么颜色的光了?
(2)另一方面,使抗原抗体结合更稳定。一般不需要,但对表达较弱的抗原可能有用,4度和37度时分子运动方式不同,前者分子碰撞机率和运动速度小于后者,后者结合更快,但敏感性也提高了并易造成非特异染色。
(3)其实,我更赞同后一种说法,因为我尝试把肝脏或睾丸片子从4度过夜拿出后,直接用PBS洗没发生过脱片现象。事实胜于雄辩!
