Protocol

Cell experiment [1]:

Cell lines

Cultured human subcutaneous fibroblasts.

Preparation method

Soluble to 0.50 mg/ml in sterile water. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions

100 μM.

Applications

In cultured human subcutaneous fibroblasts, 10panx decreases the bradykinin-induced [Ca2+]i response and attenuates bradykinin (30 μM)-induced ATP release [1]. In oocytes, 10panx inhibits pannexin1 currents. In oocytes expressing pannexin1, 10panx attenuates dye uptake by pannexin1 channels [2].

Background

スクランブルされた10Panxは、パネキシン1の模倣ペプチドである10Panx(WRQAAFVDSY)のスクランブル形です。このペプチドは、細胞膜電流に影響を与えずにマクロファージの染料取り込みを抑制します。アンテルペプチドPanxE1Bと構造的に類似しているが、3つのアミノ酸が短くなっていますが、卵母細胞中でパネキシン1電流を同等程度に抑制する効果を発揮します。 10Panxはまた、I2ndの活性化を阻止し、ブラジキニン誘導性[Ca2+] i 応答を減少させ、キナクリンでロードされた人間線維芽細胞からのブラジキニン誘発性ATP放出も低下させます。ただし、いくつかの研究では、スクランブルした10Panxは本来の形式よりも効果が低いことが証明されています。

%DMSO %

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
