CD40

CD40,即腫瘤壞死因子受體超家族成員5(TNFRSF5),別名Bp50、CD40L等。CD40由人類CD40基因編碼,廣泛表達(dá)于免疫細(xì)胞,特別是B細(xì)胞、樹突狀細(xì)胞(DC)和單核細(xì)胞。CD40是一種單鏈型跨膜蛋白,包括一個(gè)胞外區(qū)域、一個(gè)跨膜區(qū)域和一個(gè)胞漿區(qū)域,其胞外區(qū)域可以與其配體CD40L(CD40配體)結(jié)合,觸發(fā)信號(hào)傳導(dǎo)。CD40在連接先天免疫和適應(yīng)性免疫方面發(fā)揮著重要作用,其功能擴(kuò)展到B細(xì)胞激活、抗原呈遞和炎癥調(diào)節(jié)等多個(gè)層面。CD40對(duì)于體液免疫應(yīng)答、免疫記憶的形成以及免疫調(diào)節(jié)都具有重要意義。CD40信號(hào)傳導(dǎo)也在免疫治療研究中被廣泛研究,以開發(fā)新的治療方法來增強(qiáng)或抑制免疫系統(tǒng)的特定響應(yīng)。

CD40 Recombinant Monoclonal Antibody (CSB-RA004936MA1HU)

驗(yàn)證數(shù)據(jù)

CSB-RA004936MA1HU

Immunofluorescence staining of A549 cell with CSB-RA004936MA1HU 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 FITC-conjugated AffiniPure Goat Anti-mouse IgG(H+L).

CSB-RA004936MA1HU

Immunofluorescence staining of PC-3 cell with CSB-RA004936MA1HU 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 FITC-conjugated AffiniPure Goat Anti-mouse IgG(H+L).

CSB-RA004936MA1HU

Overlay Peak curve showing THP-1 cells surface stained with CSB-RA004936MA1HU (red line) at 1:100. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated Goat Anti-Mouse IgG(H+L) at 1/200 dilution for 35 min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1μg/1*106cells) used under the same conditions. Acquisition of >10,012 events was performed.
