The bovine IFN-γ ELISAPRO kit provides all necessary reagents and solutions required to quantify bovine IFN-γ in solution, e.g. in cell culture supernatant, and serum/plasma samples. The kit contains an ELISA plate pre-coated with monoclonal capture antibody, biotinylated detection antibody, Streptavidin-HRP, TMB substrate, ELISA standard and ELISA diluent. The ELISA diluent prevents false positive read-outs which may be caused by heterophilic antibodies found in serum and plasma samples.
Pre-coated ELISA plates save time and reduce assay variability.
Species cross-reactivityThe monoclonal antibodies in this kit cross-react with IFN-γ from sheep. See the Veterinary table
Analyte Information
IFN-γInterferon-γ (IFN-γ, also known as IFN-gamma, IFN-g, IFNg and Interferon-gamma) is produced mainly by activated T cells and NK cells. It is a proinflammatory cytokine that activates macrophages and endothelial cells, but it also regulates immune responses by effecting APC and T and B cells. Production of IFN-γ by helper T cells as well as cytotoxic T cells is a hallmark of the TH1-type phenotype, thus, high-level production of IFN-γ is typically associated with effective host defense against intracellular pathogens.

比如,你使用了小鼠IgG1, PE 标记的特异性抗体,那就选用小鼠IgG1, PE标记的非特异性抗体。
下面这个图,是一个比较典型的使用了同型对照的结果图向左转|向右转灰色的曲线是未染色的样本,黄色是同型对照,红色是特异性抗体染色。由于细胞对抗体的非特异性结合,一般同型对照都会比未染色样本的荧光信号要强。所以设置阴性阈值的时候,要根据同型对照,而不是未染色的细胞。
请问各位大神,需要做人巨噬细胞的F4/80,CD11b,CD163标记物,用流式,抗体哪家比较好呢,请推荐,谢谢!
能用的条件:1.分子的小鼠和人差异小,2.小鼠细胞本身不含有鼠抗体的结合受体;
不能用的条件:1.分子种属间差异大,2.采用的小鼠细胞株表面有鼠抗体的结合受体。
推荐尽量采用抗鼠的抗体,义翘神州兔单抗技术做出来的FCM抗体不少,可以到官网搜一下看看。
利用CD3/CD4/IL-17的抗体组合(不同荧光素标记),具体步骤可按照淋巴细胞TH1/2亚型分析的protocol!
一般都是先做CD4的surface staining
然后再做IFN-gamma和IL-17的intrecellular staining
对于日常的肿瘤细胞株而言,大多数两种培养液都是可以的,但是有一点,就是在同一个细胞株中间不要频繁的切换两种培养液,因为毕竟两种培养液的成分有不同,在切换的过程中细胞有一个适应的过程,而这个过程中细胞的状态就不是很好,会出现黑色颗粒的物质。
