Creative Biolabs社は、Fab断片(Fab fragment)の抗体生産の専門会社です。Fabフラグメントは、VH、CH1、VLおよびCL1の4つのドメインからなる特別な抗体です。440から450個のアミノ酸を有し、その分子量は約47～48kDaです。抗体全体と比較して、Fab断片にはいくつか利点がありますが、一方では、組織に浸透しやすく、大腸菌などのより単純な発現系によって生成することができ、一方では、Fab断片はFc領域を欠くので、Fc部分とFc受容体との間の相互作用が除去されます。したがって、Fabフラグメントは、抗体特異性を増強し、エフェクター機能を低下させるのです。Fabフラグメント抗体は、ますます重要になってゆきます。現在、Abciximab (ReoPro®)、ranibizumab (Lucentis®)およびcertolizumab pegol (Cimzia®)の3つのFabフラグメント抗体が市販されております。Creative Biolabsの科学者も、お客様のご要求にお応えするべく、より多くのFabフラグメント抗体を生産するために懸命に取り組んでいます。
