Reported findings and study design
Purification yielded a polypeptide with a mass of 4,749 ± 2 Da and structural similarity to the N-terminal region of a Gₒ-protein alpha subunit.
Reversed-phase HPLC, circular dichroism and proteomic comparison.
| Measure | Result | Comparison, timing and statistics |
|---|---|---|
| Mass after purification | 4,749 ± 2 Da | A polypeptide isolated from Wistar rat brain by reversed-phase HPLC. |
| Proteomic comparison | Similarity to an N-terminal Gₒ-protein alpha-subunit fragment | The later PPC-M paper cites this earlier rat-tissue work. The candidate is distinct from the material directly characterized in PPC-M. |
This is a molecular characterization result from a distinct rat-brain preparation.
