dbco-peg4-biotin

DBCO-PEG4-Biotin (ADIBO-NH-PEG2-Biotin) 是一种 azadibenzocyclooctyne-biotin 衍生物，含有生物素基团和 4 个 PEG。DBCO-PEG4-Biotin 是一种用途广泛的生物素酰化试剂，能通过无铜催化烷基叠氮化反应 (SPAAC) 将生物素的一部分引入叠氮标记的生物分子中。

Dde Biotin-PEG4-DBCO is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.

DBCO-SS-PEG4-Biotin is a cleavable link mid-functional ADC linker composed of a 4-unit PEG moiety. It finds utility in the synthesis of antibody-drug conjugates (ADCs)[1].

N-(DBCO-PEG4)-N-Biotin-PEG4-NHS is a PEG-based PROTAC linker suitable for synthesizing PROTACs[1].

Biotin-PEG4-SS-azide 是一种可降解的、生物素标记的 ADC linker，用于合成 ADCs。作为一种点击化学试剂，它含有 Azide 基团，可以与含有 Alkyne 基团的分子发生铜催化的叠氮-炔环加成反应（CuAAc)；也能与含有 DBCO 或 BCN 基团的分子发生菌株促进的炔-叠氮环加成反应 (SPAAC)。
