ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 1D3 is a ZooMAb® recombinant rabbit monoclonal antibody that specifically detects CD163. It targets an epitope within 17 amino acids from the N-terminal extracellular domain.

Immunogen

KLH-conjugated linear peptide corresponding to 17 amino acids from the N-terminal extracellular domain of human CD163.

Application

Quality Control Testing

Evaluated by Western Blotting in human liver tissue lysate.

Western Blotting Analysis: A 1:10,000 dilution of this antibody detected CD163 in human liver tissue lysate.

Tested Applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected CD163 in lysate from human spleen tissue.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected CD163 in human liver tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound CD163 peptide with at least ten thousand-fold (10,000X) higher than with non-specific control peptide.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

Scavenger receptor cysteine-rich type 1 protein M130 (UniProt: Q86VB7; also known as Hemoglobin scavenger receptor, CD163) is encoded by the CD163 (also known as M130) gene (Gene ID: 9332) in human. CD163 is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-41), which is subsequently cleaved off to produce the mature form that contains a long extracellular domain (aa 42-1050), a transmembrane domain (aa 1051-1071), and a cytoplasmic domain (aa 1072-1156). CD163 is expressed in monocytes and mature macrophages with high expression observed in bone marrow macrophages, Kupffer cells, lung macrophages, and red pulp macrophages. Its levels are up regulated by anti-inflammatory mediators and suppressed by pro-inflammatory mediators like lipopolysaccharides (LPS) and TNF. It serves as an acute phase-regulated receptor involved in clearance and endocytosis of Hb/Hp complexes by macrophages and protects tissues from free hemoglobin-mediated oxidative damage. The binding of the Hb/Hp complex to CD163 macrophages leads to a fast degradation of the complex. CD163 also plays a role in the uptake and recycling of iron, via endocytosis of Hb/Hp complex and subsequent breakdown of heme. A soluble form of CF163 (sCD163) has also been described that is produced by proteolytic shedding and can be induced by LPS, phorbol ester, and Fc region of immunoglobulin. This soluble form plays an anti-inflammatory role and is considered a diagnostic parameter for monitoring macrophage activation in inflammatory conditions. Its expression is markedly induced by anti- inflammatory mediators, such as glucocorticoids and interleukin 10. Clone MAC2-158 binds to SRCR domain 1 of CD163 and recognizes over 80% of circulating CD14-expressing monocytes. This ZooMAb® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
