これまで本発明の好ましい実施形態及びそれらの改変形態を詳細に説明したが、本発明がこれらの実施形態及び改変形態に限定されず、添付される特許請求の範囲に定められる本発明の精神及び範囲を逸脱することなく当業者によってその他の改変及び変形が実施され得ることは当然である。
通常の顕微鏡による撮像の前に組織試料を染色するために多数の染色剤及び染料が病理学で用いられる。いくつかの染色剤は無毒であり、生体内で癌腫瘍に優先的に結合する。これらの発色団は生体染色剤と呼ばれ、本発明に関して特に注目され、有用である。特に、非局在化陽イオン電荷をもつ染料または染色剤は腫瘍において選択的な結合及び保持が可能である。これらには、ローダミン123のようなローダミン、フェノチアジニウム染料、メチレンブルー及びトルイジンブルーがある。生体内でコラーゲンに結合する赤−ピンク染色剤である、ローズベンガル及びエオシンのようなその他の生体染色剤を用いることができる。

発色団または光増感剤は必要に応じて目標成分に連結させることができる。好ましい実施形態において、目標成分は抗体である。抗体成分は腫瘍細胞の表面に存在するエピトープに特異的に結合することができる。「特異的結合」は、抗体が非癌細胞に選択的に結合しないか、または非癌細胞が抗体によって僅かにしか認識されないことを意味する。抗体には、完全自然抗体、二価抗体、キメラ抗体、Fab、Fab'、単鎖V領域フラグメント(scFv)及び融合ポリペプチドを含めることができる。抗体はモノクローナルであることが好ましい。本実施形態において、担体分子、例えば抗体は、腫瘍細胞または癌腫瘍のその他の成分への発色団の結合に対するさらなる特異性を与えた。
