Description

Scrambled 10Panx is the scrambled form of 10Panx (WRQAAFVDSY), a mimetic peptide of pannexin 1 that inhibits dye uptake by macrophages without affecting cellular membrane currents. Being structurally similar to anther peptide PanxE1B, 10Panx is three amino acid shorter but exerting an inhibitory effect against pannexin1 currents in oocytes to a similar extent as PanxE1b. 10Panx is also able to block the activation of I2nd, decrease the bradykinin-induced [Ca2+]i response and attenuate bradykinin-induced ATP release from human fibroblasts loaded with quinacrine. However, in several studies, scrambled 10Panx has been proved to be less effective than 10Panx in its authentic form.

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].
