产品介绍

Guanylin(human) TFA，一种 15 个氨基酸的肽，是一种内源性肠鸟苷酸环化酶 (intestinal guanylate cyclase) 激活剂。Guanylin(human) TFA 主要存在于胃肠道中，其通过 cGMP 依赖性机制调节肠和肾上皮中电解质水的运输。

生物活性

Guanylin(human) TFA, a 15-amino acid peptide, is an endogenousintestinalguanylate cyclaseactivator. Guanylin(human) TFA is mainly found in gastrointestinal tract which regulates electrolytead water transport in intestinal and renal epithelia through cyclic GMP-dependent mechanism^[1]^[2].

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.
