Target Background

Function
KCNT1 is an outwardly rectifying potassium channel subunit that can coassemble with other Slo-type channel subunits. It is activated by high intracellular sodium or chloride levels and is triggered upon stimulation of G-protein coupled receptors, such as CHRM1 and GRIA1. KCNT1 may be regulated by calcium in the absence of sodium ions (in vitro).

Q&A

What is KCNT1 and why is it important for neurological research?

KCNT1 (Potassium Channel, Subfamily T, Member 1) is a sodium-activated potassium channel subunit that functions in ion conductance and developmental signaling pathways. It represents one of the more complex voltage-gated ion channels with diverse functions including regulating neurotransmitter release, neuronal excitability, and cellular volume . The significance of KCNT1 in neurological research stems primarily from its association with severe early-onset epileptic disorders. Mutations in the KCNT1 gene cause early-onset epileptic disorders including malignant migrating partial seizures of infancy and autosomal dominant nocturnal frontal lobe epilepsy . These gain-of-function mutations increase the activity of KNa1.1 sodium-activated potassium channels, resulting in hyperactive channel function that contributes to epileptogenesis . The relationship between specific KCNT1 mutations and clinically distinct phenotypes makes this channel a critical target for both basic epilepsy research and the development of targeted therapeutics.

What applications is the KCNT1 Antibody, Biotin conjugated suitable for?

The KCNT1 Antibody, Biotin conjugated (ABIN2482927) has been validated for multiple experimental applications, making it a versatile tool for researchers. It is suitable for:

  • Western Blotting (WB) - Detects KCNT1 protein at approximately 140 kDa

  • Immunohistochemistry (IHC) - For tissue section analysis

  • Immunofluorescence (IF) - For cellular localization studies

  • Immunocytochemistry (ICC) - For cultured cell analysis

  • Antibody Array (AA) - For high-throughput protein detection

For optimal results in each application, proper optimization is necessary. In Western blotting, researchers should use protein G-purified antibody preparations and verify molecular weight against the expected 140 kDa band. For immunofluorescence applications, the biotin conjugation allows for amplification strategies using streptavidin-based detection systems, which can significantly enhance sensitivity when studying KCNT1 in neuronal tissues where expression may be regionally specific.

What is the specificity profile of the KCNT1 Antibody, Biotin conjugated?

The specificity profile of KCNT1 Antibody, Biotin conjugated (ABIN2482927) is characterized by:

  • Target epitope: Amino acids 1168-1237 of rat Slo2.2 (Slack)

  • Host species: Mouse monoclonal antibody (clone N3-26, formerly S3-26)

  • Isotype: IgG1

  • Cross-reactivity: Human (weak), Mouse, Rat (strongest reactivity)

  • Specificity: Detects protein at approximately 140 kDa

  • Does not cross-react with: KCNT2/Slo2.1/Slick

This antibody demonstrates high specificity for KCNT1 over the closely related KCNT2 channel, making it particularly valuable for discriminating between these channel subtypes in experimental systems. The weak human detection should be noted when designing experiments with human samples, potentially requiring higher antibody concentrations or enhanced detection methods. Researchers should conduct validation experiments in their specific model systems to confirm specificity before proceeding with detailed analyses.

How should I optimize Western blot protocols for detecting KCNT1?

When optimizing Western blot protocols for KCNT1 detection using the biotin-conjugated antibody, consider the following methodological approaches:

  • Sample preparation:

    • For cell lysates: Use RIPA buffer with protease inhibitors

    • For tissue homogenates: Homogenize in ice-cold PBS with 1% Triton X-100 and protease inhibitors

    • Heat samples at 70°C instead of 95°C to prevent aggregation of membrane proteins

  • Gel selection:

    • Use 4-15% gradient gels for optimal resolution of the ~140 kDa KCNT1 protein

    • Lower percentage gels (7.5%) can also provide good separation for high molecular weight proteins

  • Transfer conditions:

    • Use 0.45μm nitrocellulose membranes rather than PVDF for this antibody

    • Perform transfer at lower voltage (30V) overnight at 4°C for complete transfer of large proteins

    • Leverage the biotin conjugation by using streptavidin-HRP for detection

    • Dilution range: Start with 1:2000 as used in validated protocols

    • For weaker signals (especially human samples), consider signal amplification systems

  • Controls:

    • Include rat brain lysate as a positive control

    • For negative controls, use tissues known to express minimal KCNT1

    • Consider including KCNT1 knockout samples if available

This optimization approach has been validated in multiple studies examining KCNT1 expression and has shown reliable detection with minimal non-specific binding .

How can I distinguish between KCNT1 splice variants using antibody-based methods?
