VEGFA

VEGFA,全稱血管內(nèi)皮生長(zhǎng)因子A,是一種重要的蛋白質(zhì),在血管生成和腫瘤生長(zhǎng)中發(fā)揮關(guān)鍵作用。它也被稱為血管通透性因子(VPF),能夠促進(jìn)內(nèi)皮細(xì)胞增殖、遷移,并抑制細(xì)胞凋亡,從而增強(qiáng)血管通透性。VEGFA通過與受體VEGFR1和VEGFR2結(jié)合,激活下游信號(hào)通路,促進(jìn)血管內(nèi)皮細(xì)胞增殖和遷移,進(jìn)而誘導(dǎo)血管生成。此外,VEGFA還能影響免疫細(xì)胞功能,如抑制樹突細(xì)胞成熟和破壞造血前體細(xì)胞分化,并誘導(dǎo)免疫抑制相關(guān)分子PD-L1的表達(dá),從而影響腫瘤微環(huán)境。
VEGFA與多種疾病密切相關(guān),尤其是腫瘤,如結(jié)直腸癌、非小細(xì)胞肺癌、腦膠質(zhì)瘤等。由于其在腫瘤血管生成中的重要作用,VEGFA已成為重要的藥物靶點(diǎn)。目前,全球首個(gè)上市的VEGFA單克隆抗體腫瘤藥物為羅氏開發(fā)的貝伐珠單抗(Avastin),已獲批用于多種腫瘤的治療。此外,還有多種VEGFA抑制劑正在研發(fā)中,如基石藥業(yè)的CS2009,這是一款靶向PD-1、VEGFA和CTLA-4的新型三特異性抗體,展現(xiàn)出良好的抗腫瘤活性。VEGFA相關(guān)藥物的研發(fā)為腫瘤治療提供了新的選擇。

VEGFA Recombinant Monoclonal Antibody (CSB-RA025833MA1HU)

驗(yàn)證數(shù)據(jù)

CSB-RA025833MA1HU

IHC image of CSB-RA025833MA1HU diluted at 1:50 and staining in paraffin-embedded human liver 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.

CSB-RA025833MA1HU

Immunofluorescence staining of hela cell with CSB-RA025833MA1HU 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-Rabbit IgG(H+L).

CSB-RA025833MA1HU

Immunofluorescence staining of MCF7 cell with CSB-RA025833MA1HU 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-Rabbit IgG(H+L).
