Overview
Adipotide (also written as FTPP, or by its sequence CKGGRAKDC-GG-D(KLAKLAK)2) is a proapoptotic peptidomimetic built for vascular targeting of white adipose tissue. Two functional halves are joined in a single molecule: a homing peptide, CKGGRAKDC, that binds prohibitin displayed on the endothelium of blood vessels feeding white fat, and a proapoptotic domain, D(KLAKLAK)2, that disrupts mitochondrial membranes once it is internalised. The homing sequence was originally isolated through in vivo phage-display screening for peptides that localise to white adipose tissue vasculature, which is what gives the conjugate its tissue selectivity in research models.
The molecule was characterised by researchers at the University of Texas MD Anderson Cancer Center. It is frequently discussed as a conceptual parallel to antibody-drug conjugates: the cytotoxic payload is only delivered where the targeting element has bound, so activity is concentrated at the intended vascular bed rather than distributed systemically. CertaPeptides is a reseller and supplies Adipotide as a research reagent; we do not manufacture, formulate, or select the salt form of this compound.
Research Areas
Published literature has investigated Adipotide primarily as a tool for studying adipose-tissue vascular biology and the metabolic consequences of ablating fat-feeding vasculature. In the foundational mouse work, targeted ablation of adipose vasculature was studied as a route to reversing diet-induced obesity in the model, establishing prohibitin on adipose endothelium as an addressable target (Kolonin et al., 2004). A later study in obese rhesus monkeys reported reductions in body weight and improvements in insulin resistance in the model animals over a short treatment window, with the authors examining tissue selectivity and renal markers (Barnhart et al., 2011). These two datasets remain the most cited reference points for researchers modelling vascular-targeting approaches to adipose tissue. Typical research questions include how selective prohibitin targeting is across different vascular beds, how model organisms respond to rapid loss of adipose mass, and how the conjugate format governs where apoptosis is triggered.

Quality & Verification
Every unit ships to a ≥98% supplier batch specification. In addition, selected lots are independently tested by Janoshik Analytical (HPLC and mass spectrometry), and those reports are searchable by batch code . We do not claim in-house testing and we do not test every batch — the verification tier is transparent by design: a baseline supplier specification on all units, plus third-party reports on selected lots.

Frequently Asked Questions
What is adipotide used for in research?
In the published literature, adipotide is used as a research tool to study vascular targeting of white adipose tissue. It combines a peptide that homes to prohibitin on adipose-feeding blood vessels with a proapoptotic domain, letting researchers investigate what happens in model systems when that specific vasculature is ablated. It is supplied for laboratory research only and is not approved for human or veterinary use.
How does adipotide target fat tissue specifically?
The CKGGRAKDC portion of the molecule was identified through in vivo phage-display screening for peptides that home to white adipose tissue vasculature. Its target, prohibitin, is displayed on the endothelium of fat-feeding vessels. Once the homing peptide binds, the D(KLAKLAK)2 domain is internalised and disrupts mitochondrial membranes, so activity is concentrated at the targeted vascular bed rather than distributed broadly.
What did the primate study report?
Barnhart and colleagues (2011, Science Translational Medicine) studied adipotide in obese rhesus monkeys and reported reductions in body weight and improvements in insulin resistance in the model animals over a short treatment period, alongside analysis of tissue selectivity and renal markers. This primate dataset is the most advanced preclinical reference point cited for the compound.
What is a proapoptotic peptide-drug conjugate?
It is a molecule that pairs a targeting peptide with a cell-death-inducing payload, conceptually similar to an antibody-drug conjugate. In adipotide, the targeting peptide delivers the D(KLAKLAK)2 domain to adipose endothelial cells; the payload only acts where the targeting element has bound, which is the source of the conjugate’s selectivity in research models.
How should adipotide be stored?
Store the lyophilized powder at −20°C, protected from light. After reconstitution with sterile water or PBS, keep refrigerated at 2–8°C and use within roughly 14 days. Handle in line with standard peptide-handling and institutional biosafety guidelines.
