Description

General description

Haptoglobin (UniProt: P00738; also known as Zonulin) is encoded by the HP gene (Gene ID: 3240) in human. Haptoglobin is a hemoglobin-binding acute-phase glycoprotein that is synthesized in the liver and is secreted in plasma. Although it belongs to the peptidase S1 family, it does not have any enzymatic activity. It is a tetramer of disulfide-linked two alpha and two beta chains and displays anti-inflammatory and antioxidative properties. It is synthesized with a signal peptide (aa 1-18), which is subsequently cleaved off to generate the mature form that can be further cleaved into an alpha (19-160) and a beta chain (aa 162-406). Haptoglobin complexes with free hemoglobin, resulting from erythrocyte hemolysis, and allows hepatic recycling of heme iron and prevents kidney damage. Hemoglobin/haptoglobin complex is rapidly cleared by the macrophage CD163 scavenger receptor expressed on Kupfer cells through an endocytic lysosomal degradation pathway. Its CD163 interacting region is localized to amino acids 318-323. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.

Immunogen

His-tagged full-length recombinant human Haptoglobin.

Application

Quality Control Testing

Evaluated by Western Blotting in Human liver tissue lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected Haptoglobin in Human liver tissue lysate.

Tested applications

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected Haptoglobin in human liver tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound Haptoglobin with a KD of 8.9 x 10-7 in an affinity binding assay.

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

Biochem/physiol Actions

Clone 2D22 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects human Haptoglobin.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 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.

Preparation Note

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
