  19. 免疫檢驗試劑

  20. Enzyme Immuno Assay Ex. Sandwich immunoassay

  21. Figure 1 shows an outside view of an immunoassay device based on this technology (about full size). In use, sample is added to the SAMPLE position by simply inserting a 20µl capillary pipette into the hole in the housing.  Indicator  T1 changes blue when all the sample has been absorbed. The developer solution is then added at the DEVELOPER position using a preloaded 40µl micro pipette.  Indicator T2 changes green when it is time to read the result. The length of the red RESULT line relates to the amount of analyte in the sample. The CHECK indicator must also have turned red for the result to be valid.   Figure 1 Flow-Through Control Device Patent application WO01/25789A1

  22. Figure 2 shows the printed membrane fitted inside the immunoassay device described in Figure 1 Principle of Flow Through Immuno Test

  28. 檢驗試劑未來方向

  29. 檢驗試劑之未來方向 • 診斷技術提昇:Genomic vs. Proteomics • 儀器技術提昇:電子, 網路, 自動儀技術與檢驗試劑開發相結合,更擴充檢驗試劑產品之領域及其應用 • 人類知的需求度提昇: POC及OTC市場值大增 • 人類壽命延長:保健及老年檢測增加 • Non-invasive detection • 食品衛生, 環境毒素之檢測量提昇

  30. Genome Project之影響 • 核酸檢測相關產品可取代傳統微生物培養檢驗法: 可取代近20%, 檢驗市場超過10億美元 • Human Genome Project已完成DNA定序之working draft. • 衍生: DNA Chip • 瓶頸: • target ? • Time ?

  31. Nucleic Acid Testing 舉例 • Myriad Genetics : detect MLH1 and MSH2 genes: inherited in colon cancer and uterine cancer. • Procyon: Colopath ™ : DNA in stool in rectal mucous sample • Alzheimer disease: Chromosome 10 defection

  32. Proteomics • Proteomics: important role in drug discovery, molecular diagnostics and practice of medicine in then post-genomic era • Current market value: 2 billion and will increase to 6 billion at 2005 and 10 billion at 2010 • 衍生:試劑種類增加,protein chip 產生 • 瓶頸 • S/N ratio? • Targets?

  33. Proteomics • Luminex Corp : LabMAP ™ found 300 components in disease in blood sample • Proteomics in cancer markers---Matritech

  35. 食品衛生及環境檢測 • 75 million US citizens get ill from food poisoning, 325000 hospitalized and 5000 died. • Detection of Samonella , E. Coli , campylobactor • Detection of drug residues: antibiotics: sulfa drugs, b-lactam…etc. (WTO) • Veterinary diagnosis: FMDV, pet-diagnosis • Detection of environmental toxins: dioxane, pesticide

  36. Non-Invasive Diagnosis • 非侵入性檢驗試劑之開發, 加入OTC市場 • 以檢測尿液, 唾液, 糞便等非以血液檢體為主

  37. Non-Invasive Diagnosis • Procyon: Colopath ™ : DNA in stool • 檢測尿液中之攝護腺癌之特有基因變化 (Foc Chase Cancer Center) • Nymox : 7G test in NTP marker (urine) for Alzheimer’s disease, • Calypte and Osborn HIV antibody test in urine for 15 min • Ora Sure : • OraQuick HIV test in saliva • DOA testing in oral fluid. • Calypte and Marukin • Urinary total bile acid sulfate (UBAS (liver)) • Insurance tests: HIV-1, nicotine, illegal drugs all in urine • LifePoint Test System : Salivary test in THC and PCP • Avitar: Oralscreen ™ collector can be applied in the detection of diabetes, influenza, Lyme disease, and estimate 20 billion USD revenue.

  38. 生技藥品未來方向 • 在本世紀之初於美國僅有310萬人年齡大於65歲, • 但進入21世紀時,大於65歲所謂的老年人口即將接近3千萬人, • 老年人口的增加,更加反應出針對老年疾病之檢測及治療越發的重要。 • 結至2000年已有700種藥以上為針對老年常見疾病而研發, • 104種針對心血管疾病之預防, • 354種致力於癌症的治療, • 另有241項藥物的研發為針對老年常見的疾病,如老年痴呆(19項)、骨質疏鬆(18項)…等

  39. 免疫檢驗試劑與生物藥的關係 • QC analysis method • 原料:可發展為生物藥or idea • Antibody: ex. • Magic bullet • Therapeutic vaccine • Antigen: vaccine
