CD300A
CD300A，全稱為CMRF35-like molecule 8，是一種廣泛表達的免疫調(diào)節(jié)蛋白，在自然殺傷細胞、T細胞亞群、B細胞、樹突細胞、肥大細胞等多種免疫細胞表面均有表達。該蛋白具有免疫受體酪氨酸基抑制基序，通過與磷脂酰絲氨酸等分子的相互作用，負性調(diào)節(jié)NK細胞的細胞毒性活性，并抑制肥大細胞的脫顆粒反應(yīng)。CD300A蛋白還參與調(diào)控Toll樣受體信號通路，通過激活PTPN6蛋白，負向調(diào)控MYD88介導的TLR信號傳導，從而影響免疫細胞的活化和細胞因子的產(chǎn)生。研究表明，CD300A蛋白的表達異常與血液系統(tǒng)惡性腫瘤的發(fā)生、發(fā)展密切相關(guān)，其高表達與患者生存期縮短和腫瘤微環(huán)境中NK細胞的耗竭表型相關(guān)。針對CD300A蛋白的藥物研發(fā)正在積極進行中，例如通過阻斷CD300A與配體的相互作用，增強NK細胞對癌細胞的殺傷能力，為血液惡性腫瘤和其他類型癌癥的治療提供了新的思路。

Western Blot Positive WB detected in: THP-1 whole cell lysate(30μg), HL-60 whole cell lysate(30μg), JK whole cell lysate(30μg), K562 whole cell lysate(30μg), Raji whole cell lysate(30μg), Mouse Spleen tissue lysate(30μg),Rat Spleen tissue lysate(30μg) All lanes: CD300A antibody at 1:1000 Secondary Goat polyclonal to rabbit IgG at 1/20000 dilution Predicted band size: 34,21,12,17 kDa Observed band size: 60 kDa Exposure time: 120s
IHC image of CSB-PA887023ESR1HU diluted at 1:50 and staining in paraffin-embedded human pancreatic cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB. Secondary antibody only control: uses 1% BSA instead of primary antibody
Immunofluorescence staining of HepG2 cell with CSB-PA887023ESR1HU at 1:30, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
