HPV L1 單株抗體組合
Papillomavirus的L1蛋白為主要的外鞘蛋白,分子量約為55 kD,具有自發自組裝成Virus-like particles (VLPs)的能力。

這些 VLP 所呈現的外部表面與天然的60 nm Papillomavirus病毒粒子的表面基本上是無法區分的。此外,純化的重組L1蛋白可以在沒有任何伴侶蛋白分子的情況下就能進行複雜的組裝反應,而且其組裝的VLPs也是有效的免疫原。

亞旭所代理的Creative Diagnostics 開發許多針對 HPV L1 的中和抗體,這些抗體的活性也已在pseudovirus感染檢測中得到驗證。

抗體組合資訊

抗體皆透過免疫反應並且由大腸桿菌表達的L1-VLP篩選所獲得
這些抗體對在其他不同表達系統或製程的 L1 沒有反應或是反應相對較弱
抗體已驗證在 ELISA 有效,但對 WB 無效
已使用Pseudotyped GFP HPV 確認抗體具有中和活性
每個組合包含六個clones,可以選擇不同的clone進行Sandwich ELISA分析
每個clone可以單獨出售並用於疫苗開發

其它產品
Recombinant HPV L1 VLP
Creative Diagnostics has established the global-leading virus-like particles (VLPs) manufacturing platform using the E. coli cell system. With years of exploration, our scientists have successfully obtained various highly purified HPV VLPs. Meanwhile, our products have widely contributed to HPV vaccine-related research.
 

 

Pseudotyped GFP HPV
Immunogenicity assessments in vaccine trials have focused on measuring antibody responses to the vaccine. A series of functional assays have been generated to measure antibody-mediated neutralization for papillomaviruses, while some functional assays involve highly complex animal challenges and cannot be applied for routine testing.
