Overview
Guinea pig 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 Guinea Pig (Unconjugated). This antibody is commonly used in 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 - 15/17 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- 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.
- Conjugate/format: Unconjugated (may affect detection channel and background).
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Voltage gated K+ channels are involved in diverse physiological processes ranging from repolarization of neuronal and cardiac action potential, regulation of Ca2+ signaling and cell volume to driving cellular proliferation and migration.KV2.1 consists of four α-subunits, each containing six transmembrane α-helical segments, S1-S6, and a membrane-re-entering P-loop, which are arranged circumferentially around a central pore. This ion conduction pore is lined by four S5-P-S6 sequences. The four first segments(1-4), each containing four positively charged arginine residues in the Segment number 4 helix, act as voltage sensor domains and "gate" the pore by "pulling" on the segments 4 and 5 linker.KV2.1, encoded by the KCNB1 gene, is a classical delayed rectifier channel that is involved in neuronal repolarization.
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.
