AHK-Cu

AHK-Cu, also known as Copper Tripeptide-3, is a synthetic copper-binding tripeptide composed of alanine, histidine, and lysine complexed with a copper(II) ion. It is commonly studied for its relationship to hair-follicle biology, dermal papilla cell activity, cellular proliferation, and copper-mediated signaling pathways.

In research settings, AHK-Cu is often evaluated in models involving hair-follicle elongation, dermal papilla cell proliferation, cellular survival signaling, extracellular matrix activity, and growth-factor-associated pathways.

The Method

≥99% purity. Third-party tested. Lyophilized powder. Sterile vial integrity.

Key Research Areas

  • Hair-follicle research involving follicular elongation and growth-cycle models
  • Dermal papilla cell studies involving cellular proliferation and viability
  • Cell-survival signaling research involving apoptosis-associated pathways
  • Dermal tissue research involving fibroblast and extracellular matrix activity
  • Copper-peptide signaling and growth-factor-associated pathway investigation

Mechanism of Interest

AHK-Cu consists of the tripeptide sequence alanine-histidine-lysine coordinated with a copper(II) ion. Research has examined its interaction with dermal papilla cells, specialized cells located within the hair follicle that play an important role in follicular development and growth-cycle signaling.

Experimental studies have evaluated AHK-Cu for its effects on dermal papilla cell proliferation and survival-associated pathways. In ex vivo human hair-follicle models, AHK-Cu has also been investigated for its relationship to follicle elongation and signaling associated with cellular growth and apoptosis regulation.

Why Researchers Study AHK-Cu

AHK-Cu has gained research interest primarily because of its activity in experimental hair-follicle and dermal papilla cell models. Published laboratory research has examined its relationship to follicular elongation, dermal papilla cell proliferation, and cellular survival signaling.

It is also studied as a copper-binding peptide for investigating copper-mediated cellular signaling, dermal tissue activity, extracellular matrix pathways, and the biological processes involved in hair-follicle development and maintenance.
