Product Description

Description

The collagen hybridizing peptide (CHP) is a novel and unique peptide that specifically binds unfolded collagen chains, both in vitro and in vivo.[1,2] By sharing the Gly-X-Y repeating sequence of natural collagen, CHP has a strong capability to hybridize with denatured collagen chains by reforming the triple helical structure, in a fashion similar to DNA fragments annealing to complementary DNA strands. CHP is extremely specific: it has negligible affinity to intact collagen molecules due to lack of binding sites, and it is inert towards non-specific binding because of its neutral and hydrophilic nature.

CHP can measure and localize mechanical injury to collagenous tissue at the molecular level.[3] It also enables assessment of collagen denaturation in decellularized extracellular matrix.[4] In addition, CHP can be used to specifically visualize collagen bands in SDS-PAGE gels without the need for western blot.[5]

F-CHP is labeled with fluorescein for direct fluorescence detection.

Applications: immunofluorescence, SDS-PAGE (in-gel western)

Additional Information

CHP can slowly self-assemble into the triple helical structure in solution during storage. The trimeric CHP requires a simple heating step prior to usage. Please check the protocol for details: CHP_Datasheet.pdf
