Abstract
Description
この実験では、ターゲット検体はB型肝炎でシグナル強調物質はナノサイズの金粒子である。ナノサイズの金粒子で識別されたB型肝炎プローブはポシティブコントロールとして使用される。特に、図1にはチップウェーハ上のサンプルのマイクロアレイの概略図が示されている。チップウェーハは図1に示されるパターンに従ってスポットされている。特に、チップウェーハは6つのセクション、すなわちAからFのセクションに分割されている。セクションA、DとEは暗領域でこれらの領域はシグナル強調物質に付いているB型肝炎ウイルスプローブを持つポシティブコントロール領域を表している。ライトグレー領域、即ちセクションFはネガティブコントロールとして利用される非特異的ターゲットが投入される。白領域、即ちB,Cはスポットされたサンプルは全く含まれておらずこれらの領域はネガティブコントロールとして利用される。この配列に対しては、ポシティブ結果、即ちより暗い色がHBVプローブでスポットされた領域が観察される。一方、ネガティブ結果、即ちあまり色が付いていない他の領域で観察される。
図6A−aから図11は図1から図5bおよび上述したものと類似するデータと実験結果が示されている。特に、チップウェーハが使用され、そして同じように6つのセクション、即ち、セクションAからFに分割されている。そこにはターゲット検体が含まれるサンプルやポシティブコントロールおよび/又はネガティブコントロールが充填されている。セクションA,Dには特異的プローブが充填されている。セクションE,Fには特異的プローブが充填されているが各々100倍、10倍に希釈されている。セクションCには非特異的プローブが充填されセクションBはバッファである。図6Bを参照ください。特異的プローブはHBVプローブと似ている。この実験によると、図1から図5bに示す実験と比較すると、しかしながら、多数の差異が存在する。1つに先ず反応はチップウェーハ上で起こることが許される。そして、チップウェーハの画像が次のときに撮影されている。反応時間が6分未満(図6A−a参照)、約6分(図6A−b参照)、約10分(図6A−c参照)、約14分(図6A−d参照)、そして14分以上(図6A−e参照)のときの画像が表示されている。原則として、反応が進行するにつれて検体の存在の検出と示唆が特に明確になる時間幅が存在する。この特殊な実験においては、チップウェーハは異なった時間で白光で照射され、それに対応した画像が画像取り込み手段により取り込まれる。白単色光は目に見える範囲の波長を有する単色光である。
