SLC24A4 antibody is a laboratory reagent designed to specifically bind to and detect the SLC24A4 protein (also known as NCKX4, Sodium/potassium/calcium exchanger 4) . This antibody is predominantly used in research settings to investigate the expression, localization, and function of SLC24A4 protein across different tissue types and experimental conditions. The antibody enables researchers to study a protein that plays crucial roles in ion transport and has been implicated in various physiological processes including pigmentation regulation .
SLC24A4 antibody products are available from multiple commercial suppliers with various specifications to accommodate different research needs. These antibodies are typically produced in rabbits as polyclonal antibodies, though specifications may vary between manufacturers .
SLC24A4 (Solute Carrier Family 24 Member 4) is a transmembrane protein that belongs to the sodium/potassium/calcium exchanger family. The protein functions by transporting one calcium ion (Ca²⁺) and one potassium ion (K⁺) in exchange for four sodium ions (Na⁺) . This exchange mechanism is essential for maintaining ion homeostasis in various cellular compartments.
The SLC24A4 protein has a calculated molecular weight of approximately 69 kDa, though the observed molecular weight in experimental conditions can range from 62-90 kDa depending on post-translational modifications and experimental conditions . The gene encoding SLC24A4 is located in the human genome with the NCBI Gene ID 123041 .
SLC24A4 antibodies have been validated for multiple laboratory applications, enabling researchers to investigate this protein through various experimental approaches. The primary applications include:
These applications allow researchers to detect SLC24A4 protein in various sample types, including cell lysates, tissue sections, and protein extracts. Western blot analysis has identified the target protein in multiple cell lines and tissue types, including brain tissue, heart tissue, and HeLa cells .
For optimal results with SLC24A4 antibodies, specific experimental conditions are recommended:
For Western Blot applications, dilutions typically range from 1:500 to 1:2000, though some products allow for more dilute applications up to 1:16000 . This variation in working concentration highlights the importance of optimization for each specific experimental setup.
For immunohistochemistry applications, some suppliers recommend antigen retrieval using TE buffer (pH 9.0) or alternatively citrate buffer (pH 6.0) . The recommended dilution ranges from 1:50 to 1:500 depending on the specific antibody and application requirements.
SLC24A4 antibodies are typically produced through affinity purification methods to ensure specificity and reduce background signal . The production process generally involves:
Immunization of host animals (typically rabbits) with synthetic peptides derived from the SLC24A4 protein sequence
Collection and processing of antisera
Affinity purification using the immunogen peptide
Formulation in appropriate buffer systems for stability and performance
The final antibody products are commonly formulated in phosphate-buffered saline (PBS) containing preservatives and stabilizers such as:
Glycerol (typically 50%) for cryoprotection
Sodium azide (0.01-0.02%) as a preservative
Some formulations include bovine serum albumin (BSA) as a stabilizer, though "Azide and BSA Free" options are available for sensitive applications
Research involving SLC24A4 antibodies has contributed to understanding the biological roles of the SLC24A4 protein. This protein's function as a sodium/potassium/calcium exchanger is critical for cellular ion homeostasis in various tissues.
Genetic studies have linked variations in the SLC24A4 gene to skin/hair/eye pigmentation type 6 (SHEP6) , highlighting its potential role in determining pigmentation phenotypes. This connection makes SLC24A4 a subject of interest in dermatological and ophthalmological research.
The protein has been detected in multiple tissues, with notable expression in:

This diversity of suppliers offers researchers multiple options when selecting SLC24A4 antibodies for specific applications.
When choosing an SLC24A4 antibody for research applications, several key factors should be considered:
Validated applications: Ensure the antibody has been validated for your specific application (WB, IHC, ELISA, etc.)
Species reactivity: Verify compatibility with your experimental model (human, mouse, rat, or other species)
Immunogen information: Consider the region of the protein used as immunogen, as this affects epitope recognition
Formulation requirements: Some applications may require specific formulations (e.g., azide-free, BSA-free)
Validation data: Review available data showing specificity and performance in relevant applications
Publication record: Consider antibodies with established track records in peer-reviewed publications
These considerations help ensure selection of appropriate reagents for specific research objectives.
Manufacturers employ various validation methods to confirm the specificity and functionality of SLC24A4 antibodies. These typically include:
Western blot analysis using positive control samples (e.g., Raw 264.7 cells, mouse brain tissue, HeLa cells)
Immunohistochemistry on tissue sections known to express the target protein
Validation across multiple reactive species to confirm cross-reactivity claims
Determination of optimal working dilutions for different applications
These validation processes help ensure that antibodies perform as expected in laboratory settings and produce reliable, reproducible results.
Quality control measures for SLC24A4 antibodies typically include:
Batch-to-batch consistency testing
Specificity verification using positive and negative control samples
Application-specific performance testing
Stability testing under recommended storage conditions
Many suppliers provide certificates of analysis (COA) for specific lots or batches, allowing researchers to review quality control data for their specific product . These quality assurance processes contribute to the reliability of research findings generated using these antibodies.
