General description

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Green Chemistry.This antibody is Preservative-free, produced without the harm or sacrifice of animals and exceptionally stable to allow for ambient shipping and storage if needed and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency". Click here for more information.
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.


Clone 1B2 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Multidrug resistance-associated protein 2 ( MRP2). It targets an epitope within 14 amino acids from the C-terminal, cytoplasmic domain.


KLH-conjugated linear peptide corresponding to 14 amino acids from the C-terminal, cytoplasmic domain of human Multidrug resistance-associated protein 2 ( MRP2).

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected MRP2 in A549 cells.

Immunohistochemistry (Paraffin) Analysis: A 1:500 dilution from a representative lot detected MRP2 in human liver tissue sections.

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

Target description

ATP-binding cassette sub-family C member 2 (UniProt: Q92887; also known as Canalicular multidrug resistance protein, Canalicular multi-specific organic anion transporter 1, Multidrug resistance-associated protein 2, MRP2) is encoded by the ABCC2 (also known as CMOAT, CMOAT1, CMRP, MRP2) gene (Gene ID: 1244) in human. MRP2, a member of the family of human ATP-binding cassette (ABC) transporters, binds and hydrolyzes ATP to enable active transport of various substrates, including many drugs, toxicants, and endogenous compound across cell membranes. It transports a wide variety of conjugated organic anions such as sulfate-, glucuronide- and glutathione (GSH)-conjugates of endo- and xenobiotics substrates. It is reported to mediate hepatobiliary excretion of mono- and bis-glucuronidated bilirubin molecules. Hence, it plays an important role in bilirubin detoxification. MRP2 is expressed in the apical hepatocyte plasma membrane, renal proximal tubules, and small intestine, where it plays a role in the elimination and oral bioavailability of drugs, xenotoxins, and their metabolites. It also confers resistance to several anti-cancer drugs, including cisplatin, doxorubicin, epirubicin, methotrexate, etoposide, and vincristine. It contains two conserved nucleotide-binding domains (aa 671-678 and 1334-1341) that mediate the binding and hydrolyzing ATP via an ATPase, thereby providing energy for substrates export from the cytoplasm to the extracellular space. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.


30 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.
