Crustacean cardioactive peptide，free acid is a highly conserved, amidated cyclic nonapeptide, first isolated from the pericardial organs of the shore crab Carcinus maenas, where it has a role in regulating heartbeat; Crustacean cardioactive peptide，free acid also modulates the neuronal activity in other arthropods.

Ultrabithorax and Abdominal-A are not necessary for specification of the CCAP-interneurons, but are absolutely required to prevent the death by apoptosis of the CCAP-efferent neurons^[2].

CCAP, FMRFamide and SALDKNFMRFamide increase the mosquito antennal accessory pulsatile organ (APO) and heart contraction rates, increase hemolymph flow velocity in the antennal space^[1].

• 方案 一

  请依序添加每种溶剂： 10% DMSO    40% PEG300    5% Tween-80    45% Saline

  Solubility: ≥ 2.5 mg/mL (2.61 mM); 澄清溶液

  此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。

  以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；再向上述体系中加入 50 μL Tween-80，混合均匀；然后再继续加入 450 μL 生理盐水 定容至 1 mL。

  生理盐水的配制：将 0.9 g 氯化钠，溶解于 ddH₂O 并定容至 100 mL，可以得到澄清透明的生理盐水溶液。

• 方案 二

  Solubility: ≥ 2.5 mg/mL (2.61 mM); 澄清溶液

  此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。

  以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中，混合均匀。

  20% SBE-β-CD in Saline 的配制（4°C，储存一周）：2 g SBE-β-CD（磺丁基醚 β-环糊精）粉末定容于 10 mL 的生理盐水中，完全溶解至澄清透明。

• 方案 三

  请依序添加每种溶剂： 10% DMSO    90% Corn Oil

  Solubility: ≥ 2.5 mg/mL (2.61 mM); 澄清溶液

  此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液，此方案实验周期在半个月以上的动物实验酌情使用。
