Description
In Vitro
Calcitonin Gene Related Peptide (CGRP) II, rat induces vasodilator effects in small-diameter pig left anterior descending (LAD) coronary arteries with an EC50 value of 0.56 nM[1].
Calcitonin Gene Related Peptide (CGRP) II, rat relaxes the spontaneous tone in isolated internal anal sphincter (IAS) strips, with an EC50 value of 83 μM[2].
Calcitonin Gene Related Peptide (CGRP) II, rat (rβCGRP) inhibits [125I]hαCGRP binding (IC50: 7 nM), and stimulates cAMP accumulation (EC50: 0.56 nM) in the cells co-expressing mRAMP1 (mouse receptor-activity-modifying-protein 1) and rCRLR (rat calcitonin receptor-like receptor)[3].
Calcitonin Gene Related Peptide (CGRP) II, rat (rat-βCGRP, 0.01-100 nM) induces endothelium-independent relaxations in the coronary arteries from male and female Sprague-Dawley rats, with an IC50 value of 2.8 nM approximately[4].

Peptide Solubility and Storage Guidelines:
1. Calculate the length of the peptide.
2. Calculate the overall charge of the entire peptide according to the following table:
| Contents | Assign value | |
|---|---|---|
| Acidic amino acid | Asp (D), Glu (E), and the C-terminal -COOH. | -1 |
| Basic amino acid | Arg (R), Lys (K), His (H), and the N-terminal -NH2 | +1 |
| Neutral amino acid | Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) | 0 |
3. Recommended solution:
| Overall charge of peptide | Details |
|---|---|
| Negative (<0) |
1. Try to dissolve the peptide in water first. 2. If water fails, add NH4OH (<50 μL). 3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide. |
| Positive (>0) |
1. Try to dissolve the peptide in water first. 2. If water fails, try dissolving the peptide in a 10%-30% acetic acid solution. 3. If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO. |
| Zero (=0) |
1. Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first. 2. For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration. |
