What 5TAMRA-GRTGRRN-Ser(PO3H2)-I is studied for

  • Receptor-binding and functional selectivity studies
  • Second-messenger (cAMP / IP₁) profiling
  • Hypothalamic–pituitary axis feedback modeling
  • Metabolic and glucose-homeostasis research

Mechanism of action

5TAMRA-GRTGRRN-Ser(PO3H2)-I sits within the Endocrine research class (CPC reference PROK-053). Endocrine peptides bind class A/B GPCRs and RTKs on hormone-responsive tissues, triggering canonical cAMP, IP₃/Ca²⁺, and MAPK pathways that regulate secretion, growth, and metabolism. Investigators typically incorporate 5TAMRA-GRTGRRN-Ser(PO3H2)-I as a reference standard, tool ligand, or substrate in the assay contexts listed above. HTRF cAMP, calcium mobilization (FLIPR), and radioligand binding are the standard readouts.

Frequently asked questions

What is 5TAMRA-GRTGRRN-Ser(PO3H2)-I?

5TAMRA-GRTGRRN-Ser(PO3H2)-I (CPC catalog code PROK-053) is a synthetic endocrine research peptide in the endocrine category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

What is 5TAMRA-GRTGRRN-Ser(PO3H2)-I studied for?

Published and internal research programs use 5TAMRA-GRTGRRN-Ser(PO3H2)-I as a reference standard in endocrine workflows — for example, receptor-binding and functional selectivity studies and second-messenger (camp / ip₁) profiling. Human clinical evidence is not established.

Is 5TAMRA-GRTGRRN-Ser(PO3H2)-I FDA-approved for human use?

No. 5TAMRA-GRTGRRN-Ser(PO3H2)-I 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 5TAMRA-GRTGRRN-Ser(PO3H2)-I typically used in the lab?

In a endocrine workflow, 5TAMRA-GRTGRRN-Ser(PO3H2)-I is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. HTRF cAMP, calcium mobilization (FLIPR), and radioligand binding are the standard readouts.

How should 5TAMRA-GRTGRRN-Ser(PO3H2)-I be stored?

Store lyophilized at −20 °C, protected from light. Reconstitute in sterile 0.1% BSA/PBS. Follow your institution's standard operating procedures for handling synthetic peptides.

Where does the 5TAMRA-GRTGRRN-Ser(PO3H2)-I product page point to?

This kindr reference page mirrors CPC Scientific's catalog metadata for PROK-053. 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 5TAMRA-GRTGRRN-Ser(PO3H2)-I?

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.
