BigLEN(mouse) is a potent and selective agonist of orphan G protein-coupled receptor 171 (GPR171), with a Kd of ∼0.5 nM. BigLEN(mouse) can be used to regulate responses associated with food intake and metabolism.
Kd: ∼0.5 nM (GPR171)
Room temperature in continental US; may vary elsewhere.
2.;;Calculate the overall charge of the entire peptide according to the following table:
Acidic amino acid
Asp (D), Glu (E), and the C-terminal -COOH.
Basic amino acid
Arg (R), Lys (K), His (H), and the N-terminal -NH2
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)
Overall charge of peptide
1.;;Try to dissolve the peptide in water first. 2.;;If water fails, add NH4OH (lt;50 μL). 3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
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.
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.
