Rabbit Polyclonal Hemopexin/HPX (V97-A447) Antibody (Human, Mouse, Rat) – Research Use Only

Rabbit Polyclonal Hemopexin/HPX (V97-A447) Antibody (Catalog #B2023349) is a 100 µg affinity-purified polyclonal antibody raised against amino acids V97-A447 of human hemopexin. This antibody recognizes hemopexin (HPX) across human, mouse, and rat species. Hemopexin is the primary plasma protein responsible for high-affinity heme binding and transport. The antibody is suitable for detecting endogenous hemopexin in Western blotting, immunohistochemistry, immunofluorescence, and immunoprecipitation applications in multiple species.

Scientific Overview

Hemopexin (HPX) is a 57 kDa plasma glycoprotein that binds free heme with extremely high affinity, protecting tissues from heme-mediated oxidative damage and facilitating safe heme delivery to the liver. The epitope region V97-A447 covers a conserved portion of the protein, enabling cross-reactivity with human, mouse, and rat hemopexin. This rabbit polyclonal antibody is a reliable tool for detecting endogenous hemopexin in biochemical, cellular, and tissue-based studies of heme metabolism, oxidative stress, acute-phase responses, hemolysis, and related pathologies.

Recommended applications include:

• Western Blot detection of hemopexin (~57 kDa band) in serum, plasma, or tissue lysates
• Immunohistochemistry and immunofluorescence for localization in tissues
• Immunoprecipitation for pull-down of hemopexin complexes
• ELISA for quantitative measurement of hemopexin levels

Usage & Handling Guidance

Reconstitute the lyophilized antibody in sterile ultrapure water or PBS to a concentration of 0.5–1 mg/mL. Prepare single-use aliquots and store at −20°C. Avoid repeated freeze–thaw cycles. For Western Blot, a typical starting dilution is 1:500–1:2000; optimize for your specific system.

• Recommended dilutions: WB 1:500–1:2000; IHC/IF 1:100–1:500 (optimize empirically)
• Blocking: Use 5% non-fat milk or BSA in TBST
• Secondary antibody: HRP- or fluorophore-conjugated anti-rabbit IgG
• Positive control: Human or rodent serum/plasma, liver tissue lysates
