G1-S

Why It Matters
The GLP-1 receptor family is one of the most actively explored targets in peptide science, of growing interest for its role in receptor signaling pathways.

What Researchers Are Studying
G1-S contains a single-sequence GLP-1 receptor peptide under investigation for receptor binding, signaling, and structure-activity relationships in non-human and in vitro models. Researchers study how these mechanisms behave in controlled laboratory settings.

Why Researchers Choose It
This single-agent peptide isolates the GLP-1 receptor pathway without stacked compounds or blends, with identity and purity documented on each batch Certificate of Analysis.

1. What is G1-S? G1-S is a single-sequence GLP-1 receptor research peptide examined in non-human research exploring receptor signaling and pathway characterization.

2. Can G1-S be studied in combination with other peptides? Research protocols vary by study design. KÖLD supplies G1-S as a single-agent compound and does not provide protocols or combination guidance.

3. Is this for human or animal use? No. All KÖLD products are for Research Use Only and are not intended for human or animal consumption, diagnosis, or treatment.

4. How is it tested? Each batch is third-party verified for identity, composition, and stability, documented on the Certificate of Analysis.

5. How is it supplied? G1-S is supplied as a lyophilized vial and is not reconstituted at the time of sale.

To preserve the integrity of your KOLD research peptides:

Before reconstitution: Store sealed vials in a freezer at -20°C (-4°F). Shield from light and humidity to protect molecular stability.

After reconstitution: Store the vial at 4°C (39°F) and use within 14 days for optimal consistency. Avoid repeated freeze-thaw cycles, which may compromise structural integrity.

Reconstitution note: Use bacteriostatic water to support extended stability under refrigeration throughout your research protocol.

This product is supplied as a lyophilized research compound and is not reconstituted at the time of sale.
If reconstitution is required for laboratory study, researchers may use KÖLD Solution, our sterile, laboratory-grade solvent.

All research compounds and solvents sold by KÖLD are intended for laboratory use only. Not for human or veterinary consumption.
