CYN 154806 TFA is a cyclic octapeptide and an effective selective somatostatin sst2 receptor antagonist. CYN 154806 TFA inhibits SRIF-induced increases in extracellular acidification (EAR) in CHO-K1 cells expressing human sst2 receptors (pKB 7.92). CYN 154806 TFA also blocks SRIF-induced increases [35S]-GTPγS binding in CHO-K1 cell membranes expressing human sst2 receptors as well as rat sst2(a) and rat sst2(b) receptors (pKB 7.81, 7.68 and 7.96, respectively).

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.

储备液配制

*下述溶液配置方法仅为基于分子量计算出的理论值。不同产品在配置溶液前，需考虑其在不同溶剂中的溶解度限制。

Concentration / Solvent Volume / Mass	1 mg	5 mg	10 mg
1 mM	0.7626 mL	3.8128 mL	7.6257 mL
5 mM	0.1525 mL	0.7626 mL	1.5251 mL
10 mM	0.0763 mL	0.3813 mL	0.7626 mL

不同实验动物依据体表面积的等效剂量转换表（参考来源于公开文献）

	小鼠	大鼠	兔	豚鼠	仓鼠	狗
重量 (kg)	0.02	0.15	1.8	0.4	0.08	10
体表面积 (m2)	0.007	0.025	0.15	0.05	0.02	0.5
Km 系数	3	6	12	8	5	20

动物 A (mg/kg) = 动物 B (mg/kg) ×	动物 B的Km系数
	动物 A的Km系数

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
