Overview
Anti-KV2.1 Antibody is an antibody targeting KCNB1, DRK1, Delayed rectifier potassium channel 1, Potassium voltage-gated channel subfamily B member 1 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IHC, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: KCNB1, DRK1, Delayed rectifier potassium channel 1, Potassium voltage-gated channel subfamily B member 1 (also reported as KCNB1, DRK1, Delayed rectifier potassium channel 1, Potassium voltage-gated channel subfamily B member 1).
- Immunogen/epitope region: Intracellular, C-terminus.
- Homology note: Mouse - identical; human, rabbit - 15/17 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Cited use: IP, ICC (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
KV2.1 is a member of the voltage-gated K+ channel superfamily. Together with the closely related KV2.2 protein they form the KV2 subfamily also known as Shab.1As with all KV channels, KV2.1 possesses the signature structure of the voltage-dependent K+ channels: six membrane-spanning domains with intracellular N and C termini. The functional KV channel is a tetramer that can either be a homotetramer or a heteromer of KV2.1 and KV2.2 subunits.Both KV2.1 and KV2.2 channels are known as delayed rectifiers that is, channels that are activated by changes in membrane potential (depolarization) but inactivate very slowly.
Research relevance and current trends
- Mapping receptor/channel localization across neuronal subtypes and subcellular compartments.
- Linking trafficking or surface expression changes to activity-dependent signaling and plasticity.
- Using KO/KD or blocking-peptide concepts to strengthen antibody-based target assignment.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-PC012.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
