Paspalicine

Paspalicine is an indole diterpenoid fungal metabolite with no tremorgenic activity in animals. Paspalicine targets the large-conductance calcium-activated potassium (maxi-K) channel, blocks channel activity, and modulates the binding of Charybdotoxin (HY-P0191) to the maxi-K channel via a positive allosteric mechanism that enhances toxin binding. Paspalicine can be used in studies related to ryegrass staggers.

Descripciòn

In Vitro

Paspalicine allosterically enhances [¹²⁵I]ChTX binding to maxi-K channels in bovine aortic smooth muscle sarcolemmal membrane vesicles, with a K₁_/₂ of 100 nM and a maximum 120% increase in specific binding relative to control^[2].
Paspalicine (10 nM; measured 3 min post-exposure) potently blocks maxi-K channels in excised inside-out membrane patches from bovine aortic smooth muscle cells, with 10 nM causing 83% current block, and the block is partially reversible after washout^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
