What Spantide II is studied for
- Incretin (GLP-1 / GIP) receptor signaling
- Appetite and satiety-circuit research
- Gastric motility and emptying assays
- Gut–brain axis and vagal signaling models
Mechanism of action
Spantide II sits within the GI / Gut research class (CPC reference SUBP-003). Gut peptides engage GPCRs on enteroendocrine cells, vagal afferents, and central nuclei, modulating motility, secretion, satiety, and glucose-dependent insulin release. Investigators typically incorporate Spantide II as a reference standard, tool ligand, or substrate in the assay contexts listed above. cAMP HTRF, in vitro islet insulin secretion, and food-intake models in rodents.
Frequently asked questions
What is Spantide II?
Spantide II (CPC catalog code SUBP-003) is a synthetic gastrointestinal / gut-hormone peptide in the gi / gut category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.
What is Spantide II studied for?
Published and internal research programs use Spantide II as a reference standard in gi / gut workflows — for example, incretin (glp-1 / gip) receptor signaling and appetite and satiety-circuit research. Human clinical evidence is not established.
Is Spantide II FDA-approved for human use?
No. Spantide II is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.
How is Spantide II typically used in the lab?
In a gi / gut workflow, Spantide II is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. cAMP HTRF, in vitro islet insulin secretion, and food-intake models in rodents.
How should Spantide II be stored?
Store lyophilized at −20 °C. Reconstitute in acidified water (0.1% acetic acid) for stability. Follow your institution's standard operating procedures for handling synthetic peptides.
Where does the Spantide II product page point to?
This kindr reference page mirrors CPC Scientific's catalog metadata for SUBP-003. The upstream reference sheet — including sequence, purity, MW, and application notes where published — is linked from the buy panel. All orders placed on kindr Peptides ship internationally under research-use terms only.
What quality specifications apply to Spantide II?
Research-grade peptides in the CPC catalog are synthesized by solid-phase peptide synthesis (SPPS), purified by preparative RP-HPLC, and characterized by analytical HPLC and mass spectrometry. Typical purity is ≥95%; certificate of analysis is available on request.
