2022年1月17日,深圳市艾倫斯文精準醫學研究所,聯合華瑞同康共同發布了抗新冠病毒IgY抗體技術。隨后,有包括人民日報、深圳特區報、南方日報等20多家媒體對此進行了報道(點擊閱讀《人民日報等多家媒體報道:抗新冠病毒IgY抗體專利技術在深發布 病毒抑制率超99%》。
近日,小編可喜地發現,深圳龍華區“龍華政府在線”英文官網也對該新型抗體技術的發布進行了全英文對外報道,報道援引了深圳特區報部分內容——

IgY antibody technology against SARS-CoV-2 unveiled
An IgY neutralizing antibody, which is claimed to inhibit the activity of SARS-CoV-2, the novel coronavirus that causes COVID-19, by over 99 percent, was launched in Shenzhen on Monday, according to Shenzhen Special Zone Daily.
The IgY antibody technology, with an invention patent issued by China National Intellectual Property Association, was jointly unveiled by Sino-Swed Tongkang Biotech Ltd. (Shenzhen) and a local precision medicine research institute.
After the COVID-19 outbreak in 2020, the two developers leveraged their strength in antibody engineering technology and began to develop antibodies that can specifically inhibit SARS-CoV-2 under the guidance of Swedish scientist Sven Skog, according to the Daily report.
The IgY antibody that shows inhibitory activity against SARS-CoV-2 was extracted and obtained from the yolks of eggs delivered by immunized hens.
The results from the Shenzhen Center for Disease Control and Prevention’s BSL-3 laboratory in October 2020 showed that the inhibitory effect of the disinfectant containing the antibody on a wild-type novel coronavirus reached 99.85 percent.
The experimental results from the State Key Laboratory of Virology in December 2021 showed that spray prepared by the antibody has an inhibitory effect of 99.94 percent on the Delta variant.
It is reported that the IgY antibody would not cause irritation or toxic side effects to the human body and can work on the body’s mucosal surfaces or on objects’ surfaces.
It has an inhibitory effect on the novel coronavirus for up to three hours per single use.

抗新冠病毒IgY抗體技術在深發布
深圳特區報訊(記者 楊明銘 吳德群)一款抗新冠病毒抗體在深問世,經雙P3實驗室驗證病毒抑制率超99%。17日,龍華區銀星科技園內,一家有著20年IgY抗體工程技術積淀與實力的生物技術公司——華瑞同康生物技術(深圳)有限公司,聯合深圳市艾倫斯文精準醫學研究所,正式發布“抗新型冠狀病毒IgY中和抗體專利技術”。
參與該項目合作研究的國家蛋白質科學中心-北京(鳳凰中心),以及武漢大學病毒學國家重點實驗室的專家,共同在線出席了本次發布會。
記者采訪獲悉,2020年新冠疫情爆發后,華瑞同康與艾倫斯文研究所充分發揮其在抗體工程技術上的優勢,在瑞典科學家Sven Skog教授帶領下,著手研發可特異性抑制新冠病毒的抗體。
本次發布的抗新冠病毒IgY抗體技術特點之一,是通過從免疫母雞的蛋黃中提取并獲得特異性抗新冠病毒抗體,完全避免了人體血清中病毒和補體交叉反應,可以特異性與病毒結合,產生抑制病毒作用。深圳市疾控中心P3實驗室在2020年10月的實驗結果顯示:該抗體制備的消毒液,對野生型新冠病毒抑制率達到99.85%。
隨后,面對新冠病毒的高變異性,武漢大學病毒學國家重點實驗室在2021年12月的實驗結果表明:該抗體制備的噴霧劑,對變異型新冠德爾塔病毒抑制率為99.94%——該實驗室負責人在發布會上連線介紹了實驗過程,并對實驗結果給予了證實和肯定。
此外,該抗新冠病毒IgY抗體還具備無毒、無害、無刺激的天然抗體優點,不會對人體帶來刺激性與毒副作用,可直接作用于皮膚粘膜表面(口腔、鼻腔),或物體表面,發揮體外抑制新冠病毒的作用;一次使用,對新冠病毒的抑制作用可長達3小時,能為使用者提供有效的體外病毒防御。
據悉,“抗新冠病毒IgY抗體”已獲得國家知識產權局頒發的發明專利證書。
