Overview
Anti-KCNN3 (KCa2.3, SK3) (N-term)-ATTO Fluor-594 Antibody is an antibody targeting Small conductance calcium-activated potassium channel protein 3, SKCa3 Polyclonal raised in Rabbit (ATTO-594. Maximum absorption 601 nm; Maximum fluorescence 627 nm. The fluorescence is excited most efficiently in the 580 - 615 nm range. This label belongs to the class of Rhodamine dyes and can be used with fluorescent equipment typically optimized to detect Texas Red and Alexa-594.). This antibody is commonly used in FC, IC, IF, IHC to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Small conductance calcium-activated potassium channel protein 3, SKCa3 (also reported as Small conductance calcium-activated potassium channel protein 3, SKCa3).
- Immunogen/epitope region: Intracellular, N-terminus.
- Homology note: Rat, mouse, pig - identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- KO-validated: yes (validation context may be assay-dependent).
- Cited use: ICC, FC (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis (unlabeled antibody, #APC-025), and immunohistochemistry (labeled antibody)..
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
KCa2.3 (KCNN3, SK3) is a member of the Ca2+-activated K+ channel family with small conductance that includes KCa2.1 (KCNN1, SK1) and KCa2.2 (KCNN2, SK2). The channel is voltage insensitive and is activated by intracellular Ca2+ in the submicromolar range. It has, though, a similar topology to that of voltage-dependent K+ channels (KV channels), that is six transmembrane domains and intracellular N- and C-termini.
Research relevance and current trends
- Linking transporter/channel abundance to ionic homeostasis and excitability-related phenotypes.
- Studying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.
- Combining antibody readouts with functional assays for more complete interpretation.
Common research applications
- 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.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
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.
- Conceptual control: KO/KD samples provide orthogonal support for target assignment when available.
- Provided control suggestions: Negative control: BLP-PC025.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
