应用
含巯基特异性基团和光敏基团的双异官能化交联剂。通常，初始反应在 pH 为 6.8 (6.5-7.0) 时通过硫醚偶联至含游离巯基的分子。紫外光 (250nm) 照射的过程中通过双自由基激发态发生二次键合。二苯甲酮对 C-H 插入表现出更大的特异性并且在水中比类似试剂更稳定。一般说来，它们附接更有效，因为可对其反复照射；然而可能需要更强的照射。与类似试剂相比，二苯甲酮对还原反应不敏感。

Treatment of murine leukaemia virus reverse transcriptase with benzophenone 4-maleimide inactivates DNA polymerase activity, but has no effect on the RNAase H function. Kinetic measurements indicated that benzophenone 4-maleimide is a competitive inhibitor with respect to template-primer binding, but is

The interaction sites of rabbit skeletal troponin I (TnI) with troponin C (TnC), troponin T (TnT), tropomyosin (Tm) and actin were mapped systematically using nine single cysteine residue TnI mutants with mutation sites at positions 6, 48, 64, 89, 104

Using a combination of cysteine mutagenesis and covalent cross-linking, we have identified subunits in close proximity to specific sites within subunit B of the vacuolar (H(+))-ATPase (V-ATPase) of yeast. Unique cysteine residues were introduced into subunit B by site-directed mutagenesis

The site-specific photocrosslinker, benzophenone-4-maleimide, was used to label G-actin specifically at Cys-374, the penultimate residue from the C terminus. The resultant BP-G-actin was polymerized to form BP-F-actin, and both forms of actin were irradiated to activate the benzophenone moiety. We

To attain light-dependent functionalization of biocompatible materials, a photolabel-derivatized, bioactive laminin fragment has been synthesized, chemically characterized, and photoimmobilized. Covalent high-resolution patterning of the laminin fragment CDPGYIGSR to hydroxylated fluorinated ethylene propylene (FEP-OH), poly(vinyl alcohol), and glycophase glass has been
