Product Overview
The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the ABC1 subfamily. Members of the ABC1 subfamily comprise the only major ABC subfamily found exclusively in multicellular eukaryotes. This protein is a retina-specific ABC transporter with N-retinylidene-PE as a substrate. It is expressed exclusively in retina photoreceptor cells, indicating the gene product mediates transport of an essental molecule across the photoreceptor cell membrane. Mutations in this gene are found in patients diagnosed with Stargardt disease, a form of juvenile-onset macular degeneration. Mutations in this gene are also associated with retinitis pigmentosa-19, cone-rod dystrophy type 3, early-onset severe retinal dystrophy, fundus flavimaculatus, and macular degeneration age-related 2.

For IHC-P, heat-induced epitope retrieval (HIER) is typically required. Recommended starting conditions: citrate buffer pH 6.0 (microwave or pressure cooker, ~20 min) for rodent samples; EDTA buffer pH 9.0 for human clinical samples. After retrieval, allow sections to cool gradually before proceeding to blocking. Include a ABCA4-positive tissue control (confirmed by literature or database expression data) and a negative isotype control in every run. Recommended dilution: IHC 1:25-1:100. Refer to the product datasheet for any target-specific retrieval guidance.
This antibody has been experimentally validated in: Human. Cross-reactivity with other species has not been systematically evaluated. If your sample species is not listed, assess immunogen sequence homology to your target species ortholog. The immunogen used is: "Synthetic peptide of human ABCA4" — higher sequence identity between species increases the probability of cross-reactivity, but experimental validation with appropriate controls is necessary before drawing scientific conclusions.
Store at -20℃ Valid for 12 months. Avoid freeze / thaw cycles. Storage Buffer: PBS with 0.05% sodium azide and 50% glycerol, PH7.4. To maintain antibody activity, avoid repeated freeze-thaw cycles. Aliquot into single-use volumes before first freeze. If working with the antibody frequently, keep a working stock at 4°C for up to 4 weeks — add 0.02% sodium azide to the working stock as a bacteriostatic agent if azide is not already present in the buffer. Monitor performance against a validated positive control when transitioning between storage aliquots or lots.
Polyclonal antibodies are produced from immunized animals and may exhibit some degree of lot-to-lot variation in titer, background, and sensitivity. Each production lot is tested for performance against established acceptance criteria. When transitioning to a new lot, run a side-by-side pilot comparison against your previous lot using a validated positive control sample before updating your standard protocol. If significant performance differences are observed, contact our technical support team — titer adjustments may resolve the issue in most cases.
Customization & Add-ons: Can't find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
