作者單位:烏普薩拉大學(xué)(瑞典語(yǔ)為Uppsala universitet),位居瑞典第一,歐洲第二十一及世界第七十一。
實(shí)驗(yàn)單位:Swedish Orphan Biovitrum公司(Sobi),現(xiàn)市值43億美元。2015年,輝瑞意圖收購(gòu)這家瑞典研發(fā)治療罕見病藥物的制藥公司。其主要研制罕見病藥物,包括白血病、自身免疫性疾病、代謝性疾病、癌癥支持療法等。主要分布在歐洲、北美、澳大利亞、新西蘭。公司在?扑庮I(lǐng)域進(jìn)行開發(fā),包括炎癥/免疫疾病、溶酶體貯積癥、血液病、肥胖癥、蛋白替代療法等。
2013 年 1 月 8 日,Swedish Orphan Biovitrum(Sobi)公司宣布,美國(guó)食品藥品監(jiān)督管理局(FDA)已批準(zhǔn)Kineret(anakinra,阿那白滯素)用于兒童與成人的早發(fā)性多系統(tǒng)炎癥性疾。∟OMID)治療。本品成為了第一也是唯一一種經(jīng) FDA 批準(zhǔn)的 NOMID 治療藥物,NOMID 是cryopyrin蛋白相關(guān)的周期性綜合征(CAPS)中最為嚴(yán)重的癥狀。這是本品第一次獲批用于兒童患者中,之前也已獲得了 FDA 的孤兒藥認(rèn)定。目前針對(duì) NOMID 患者沒有適宜的療法,而基于該藥物在療效方面的巨大潛力,本品被授予了優(yōu)先審查權(quán)。早在 2001 年,本品就獲批用于成人類風(fēng)濕性關(guān)節(jié)炎(RA)的治療。
CAPS 是一種伴隨終身并會(huì)引起人體嚴(yán)重衰弱的疾病,NOMID 則是該類別中最為嚴(yán)重的癥狀,與白介素 -1(IL-1)免疫系統(tǒng)蛋白的過度分泌有關(guān)。隨著病情的進(jìn)展,患者的聽力和視力逐漸減退,認(rèn)知功能產(chǎn)生障礙,并引起不同程度的關(guān)節(jié)變形。該藥物長(zhǎng)達(dá) 5 年的研究表明,本品除了能夠控制日常癥狀,如發(fā)熱、皮疹、頭痛、關(guān)節(jié)痛等,對(duì)于穩(wěn)定中樞神經(jīng)系統(tǒng)(CNS)的功能(如聽力和視力等)有著確切的療效。

研究目的:使用MSD ECL替代ELISA,使得檢測(cè)更快,更好。
In recombinant protein manufacturing for the purpose of producing protein-based drugs it is important to be able to demonstrate that impurities have been efficiently removed during the purification process and that the final product is pure. This project is involved in quantification of some of the impurities that may be found in a biopharmaceutical product; insulin, insulin like growth factor 1 (IGF-1) and host cell proteins (HCP). Analysis techniques that are to be used have to meet high demands in both sensitivity and in precision. Today the process related impurities are mainly analyzed with enzyme linked immunosorbent assays (ELISAs) that are available commercially as kits. However a new technique developed by Meso Scale Discovery (MSD) where the detection is based on electrochemiluminescence (ECL) technology is starting to replace ELISA. The reasons why the ECL assay may be superior to ELISA is that the measuring range is wider and the detection limit of the technique often is much lower, which means that the sensitivity is increased. Also the possibility to test multiple analytes in the same assay, a multiplex assay, reduces time and work load. This project evaluates this new technology by comparing results from the ECL assay with ELISA. Initially with one analyte at the time and if this comparison is successful the assays will be tested in a multiplex ECL assay format.
結(jié)論:
• The ECL assay is suitable for insulin and more sensitive than the ELISA currently used.
MSD電化學(xué)發(fā)光技術(shù)比ELISA更適用于胰島素檢測(cè),其靈敏度比其使用的ELISA高
• The singleplex and duplex assay for HCP generate similar signals.
宿主細(xì)胞蛋白HCP的單因子檢測(cè)和多因子檢測(cè)信號(hào)一致(使用MSD多因子技術(shù)可以在一個(gè)孔內(nèi)同時(shí)檢測(cè)宿主細(xì)胞蛋白HCP和藥物,節(jié)約時(shí)間和勞力)
