Summary

BA 1 TFA is a potent agonist for the bombesin (BB) family of receptors. BA1 binds with high affinity to Bombesin receptor subtype-3 ( BRS3 ), gastrin releasing peptide receptor ( GRPR ), neuromedin B receptor ( NMBR ) with IC ₅₀ s of 6, 0.4, 2.5 nM ^[1] .

In Vitro

BA1 (0.1 μM) significantly increases FAK tyrosine phosphorylation in BRS-3 transfected NCI-H1299 cells ^[1] .

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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 -NH ₂	+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 NH ₄ OH (<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.
