Overview
Anti-LRRC8A (extracellular) Antibody is an antibody targeting Leucine-rich repeat-containing protein 8A, Volume-regulated anion channel subunit LRRC8A, LRRC8, Swelling protein 1, SWELL1 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IF, IFC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Leucine-rich repeat-containing protein 8A, Volume-regulated anion channel subunit LRRC8A, LRRC8, Swelling protein 1, SWELL1 (also reported as Leucine-rich repeat-containing protein 8A, Volume-regulated anion channel subunit LRRC8A, LRRC8, Swelling protein 1, SWELL1).
- Immunogen/epitope region: 1st extracellular loop.
- Homology note: Rat, mouse - identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Cited use: IP, IHC (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
Leucine-rich repeat-containing 8 A (LRRC8A, SWELL1) is an essential component of the volume-regulated anion channel (VRAC) that is activated by cell swelling and ionic strength. In response to swelling, mammalian cells release chloride and organic osmolytes through VRAC channels. LRRC8A serves as a sensor of ionic strength gradient in the absence of osmotic gradient.
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
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- 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.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
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-AC001.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
