Scientific Background |
Slo1, also known as the BK (Big Potassium) channel or BKα, is a voltage- and calcium-activated potassium channel highly expressed in neurons and smooth muscle. It plays a critical role in regulating membrane excitability by facilitating the repolarization phase of action potentials and modulating neurotransmitter release. Slo1 channel activity is finely tuned by intracellular Ca²⁺ levels and membrane potential, and is further regulated by auxiliary KCNMB subunits. This dynamic regulation enables Slo1 to influence synaptic transmission, motor coordination, and responses to ethanol. Notably, Slo1 dysfunction has been implicated in a range of neurological and neuromuscular disorders, including epilepsy, ataxia, hypertension, and muscular dystrophy. Recent studies suggest that Slo1 may also contribute to neurodegenerative disease mechanisms by altering neuronal firing patterns and calcium homeostasis. Its interaction with dystrophin-related pathways further underscores its relevance in neuromuscular integrity. Given its broad physiological roles and disease associations, Slo1 is emerging as a promising target for therapeutic intervention and biomarker development in neurodegenerative research. |

Western blot analysis with Stressmarq’s Rabbit Anti- Slo1 Monoclonal Antibody, Clone S22 (SMC-625) showing detection of Human Slo1 protein in a transient over-expression (OE) lysate (OriGene LY400815). Block: 2% skim milk + 2% BSA for 1 hour at RT. Primary Antibody: Rabbit Anti-Mouse Slo1 Recombinant Monoclonal [S22] (SMC-625) at 1:1000 for 2 hours at RT. Secondary Antibody: , at 1:5000 for 1 hour at RT. Color Development: Chemiluminescent for HRP (Moss) for 30 sec at RT in the dark. Exposed 15 seconds. NOTE: The ORF clone contains a C-term DDK tag; results were confirmed using Anti-DDK antibody (OriGene TA592569), showing laddering above target is related to homooligomerization of the Slo1 protein (data not shown).
