CTLA4
CTLA4，即細胞毒性T淋巴細胞相關蛋白4，別名CD152。CTLA4是一種主要由活化的T細胞表達的跨膜蛋白，由CTLA4基因編碼。它的作用機制是通過與B7家族分子（如CD80和CD86）結合，抑制T細胞的激活和增殖，從而調節免疫反應。CTLA4的活性在自身免疫性疾病和抗腫瘤免疫中具有重要作用，其表達水平的變化可能影響免疫耐受和免疫病理過程。CTLA4的功能異常與某些自身免疫性疾病如系統性紅斑狼瘡、類風濕關節炎等有關，同時，CTLA4也是免疫檢查點抑制劑治療的靶點之一，相關藥物如伊普利姆瑪（Ipilimumab）已用于治療黑色素瘤等癌癥。

CTLA4 Recombinant Monoclonal Antibody (CSB-RA213310A0HU)
驗證數據
IHC image of CSB-RA213310A0HU diluted at 1:100 and staining in paraffin-embedded human tonsil tissue 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℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.
