产品介绍

Kisspeptin-54(human) TFA (Metastin(human) TFA) 是一种Kisspeptin受体 (KISS1，GPR54) 的内源性配体，以高亲和力结合大鼠和人类GPR54受体，其K_i值分别为 1.81 nM 和 1.45 nM。Kisspeptin-54(human) TFA 可抑制肿瘤转移并刺激促性腺激素分泌。

生物活性

Kisspeptin-54(human) TFA (Metastin(human) TFA) is an endogenous ligand forkisspeptin receptor(KISS1, GPR54). Kisspeptin-54(human) TFA binds toratandhuman GPR54 receptorswithK_ivalues of 1.81 nM and 1.45 nM, respectively. Kisspeptin-54(human) TFA hinders tumor metastasis and stimulates gonadotropin secretion^[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.
