免疫組化技術(shù)使得原位生物標(biāo)記分析可行 【?2007-06-06 發(fā)布?】 美迪醫(yī)訊
一種自動(dòng)的定量免疫組化(IHC)技術(shù)使得病理學(xué)原位生物標(biāo)記分析成為可能。 一項(xiàng)已經(jīng)向耶魯大學(xué)申請(qǐng)并在HistoRx公司投入了實(shí)踐。此項(xiàng)中主要包括了操作步驟,尤其是不同組織部分的固定方法 ,不同組織中細(xì)胞特殊部位生物標(biāo)記的定量表達(dá)不同。此項(xiàng)受保護(hù)的成果是由David Rimm博士首先發(fā)明的。 HistoRx公司的CEO說(shuō):“HistoRx公司已經(jīng)做好了提供此項(xiàng)檢測(cè)的準(zhǔn)備,熒光IHC方法,以及數(shù)碼成像技術(shù)所形成的多參數(shù)分析方 法可在病人治療前對(duì)病人的各個(gè)部分進(jìn)行分析。另有許多獨(dú)立的研究表明免疫組化技術(shù)在藥物研究和發(fā)展方面也能起到巨大的作用。 ” “我們相信這項(xiàng)技術(shù)能在藥物研究中起到顯著的作用,因?yàn)檫@種技術(shù)能快速確定藥物對(duì)接受藥物的個(gè)體來(lái)說(shuō)是否有效。”發(fā)明者 Rimm 和 Camp博士堅(jiān)持認(rèn)為。“除外,我們相信這項(xiàng)技術(shù)能為病理學(xué)家提供大量有價(jià)值的信息,出于腫瘤和其它復(fù)雜疾病診斷和預(yù)后 上的考慮。” HistoRx公司正在研發(fā)并使先進(jìn)的定量組織病理技術(shù)商品化,使蛋白生物標(biāo)記物在其組織內(nèi)定位和定量成為可能。此技術(shù)能檢測(cè) 生物標(biāo)記物亞細(xì)胞水平的濃度,并能產(chǎn)生更加準(zhǔn)確、有效、信價(jià)比最好的結(jié)果。 HistoRx同時(shí)推出了獨(dú)立的基于此技術(shù)的診斷方法,利用此技術(shù)發(fā)展而來(lái)的多參數(shù)方法能為復(fù)雜疾病提供預(yù)后方面的信息。 來(lái)源:medinews.com Immunohistochemical Technology Enables in situ Biomarker Analysis An automated quantitative immunohistochemical (IHC) technology enables in-situ biomarker analysis for pathology. A U.S. patent has been issued to Yale University (New Haven, CT, USA) and is exclusively licensed to HistoRx (New Haven, CT, USA). The patent claims the Aqua technology process, particularly the Place (pixel locale assignment for compartmentalization of expression) method, whereby biomarker expression is quantified in specific compartments of cells in tissue sections such as biopsies. The invention protected by this patent is the result of work pioneered by David Rimm, M.D., Ph.D., and Robert Camp, M.D., Ph.D., both from Yale University School of Medicine. Rana K. Gupta, Interim CEO of HistoRx said, "HistoRx is already applying Aqua analysis, fluorescent IHC methods, and digital imaging techniques to develop multiparametric assays to segment patients prior to therapy. The rapidly increasing number of independent, peer-reviewed scientific publications confirms the growing recognition of the utility of the Aqua technology in drug research and development." "We are gratified to see this patent granted because we believe Aqua technology will play a significant role in the emergence of companion diagnostics by making it possible to ensure that individual patients receive the drug that is most likely to be effective," stated the inventors, Drs. Rimm and Camp. "In addition, we believe this technology will provide the pathologist with significantly enhanced and valuable information for diagnosis and prognosis of cancer and other complex diseases." HistoRx is developing and commercializing pioneering quantitative histopathology technology that provides exceptional measurement and localization of protein biomarkers in their natural context within tissue. The Aqua technology is capable of measuring biomarker concentration with subcellular resolution to generate more precise, efficient, and cost-effective answers about the safety and effectiveness of new therapeutics in development as well as enable the development of companion diagnostic tests for targeted therapies. HistoRx is also developing independent diagnostics using Aqua technology that will utilize the multiparametric approach offered by the technology to impact prognosis and treatment decisions of complex diseases.
