Background:
Macrophage stimulating protein (MSP), also known as HGF-like protein, and scatter factor-2, is a member of the HGF family of growth factors (1). MSP is secreted as an inactive single chain precursor (pro-MSP) that contains a PAN/APPLE-like domain, four kringle domains, and a peptidase S1 domain which lacks enzymatic activity (2). Human MSP shares 79% aa sequence identity with mouse MSP and 44% aa sequence identity with human HGF. Pro-MSP is secreted by hepatocytes under the positive and negative control of CBP in complex with either HNF-4 or RAR, respectively (3). Circulating pro-MSP is proteolytically cleaved in response to tissue injury to yield biologically active disulfide linked heterodimers consisting of a 45‑62 kDa alpha and a 25‑35 kDa beta chain (4, 5). Pro-MSP can be activated by MT-SP1, a transmembrane protease that is expressed on macrophages and is upregulated in many cancers (6). Heterodimeric MSP as well as the isolated beta chain bind to MSP R/Ron with high-affinity, although only heterodimeric MSP can induce receptor dimerization and signaling (7, 8). MSP induces macrophage and keratinocyte proliferation and osteoclast activation (9, 10). It also inhibits LPS- or IFN-induced iNOS and IL-12 expression by macrophages and prevents apoptosis of epithelial cells separated from the ECM (11, 12).

如题,试剂商推荐这家的,然后网上查了一下就是武汉三鹰啊,国产的,有点虚啊?请前辈指点迷津啊
尽量使用已经用荧光素标记好的单克隆抗体。
如果是单色实验,荧光素的亮度越强越好,比如标记了APC的抗体就要比标记了pacific blue的在相同抗原量,抗体用量相同的情况下,要亮很多
如果是多色实验,除了不要使用光谱重叠度高的荧光素以外,还要搭配染色指数。简单的说,就是用亮度强的荧光素标记的抗体来染水平低的抗原,而用较弱的荧光素标记的抗体来染高表达的抗原。

anti-mouse TCR γ/δ Antibody
anti-human TCR γ/δ Antibody
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
