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.

Specificity

Clone 1C21 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Catalase. It targets an epitope within 17 amino acids from the C-terminal region.

Immunogen

KLH-conjugated linear peptide corresponding to 17 amino acids from the C-terminal region of human Catalase.

Application

Quality Control Testing

Evaluated by Western Blotting in HEK293 cell lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected Catalase in HEK293 cell lysate.

Tested applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Catalase in HeLa and L6 cell lysates.

Affinity Binding Assay: A representative lot of this antibody bound Catalase with a KD of 6.9 x 10-7 in an affinity binding assay.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected Catalase 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

Catalase (UniProt: ; also known as CAT, EC:1.11.1.6) is encoded by the CAT gene (Gene ID: 847) in human. Catalase is an antioxidant enzyme that is present in all aerobic organisms. It is predominantly localized in peroxisomes and the inner mitochondrial membrane. It catalyzes the conversion of hydrogen peroxide (H2O2) into water and oxygen and thereby protects cells from oxidative damage. Catalases can be divided into three classes: monofunctional catalase (typical catalase), catalase-peroxidase, and Mn-catalase. The first two groups are heme-containing enzymes, whereas the third group contains non-heme (manganese) catalase. Human catalase is reported to contain four identical subunits of 62 kDa and each subunit contains four distinct domains and one prosthetic heme group. The four domains include a N-terminal arm that contains a distal histidine that is reported to be important for catalase reaction; a β-barrel domain that has eight β-barrels arranged in an antiparallel fashion with six -helical insertions, creating a hydrophobic core of the protein; a connection domain that contains the tyrosine residue that binds the heme group; and an -helical domains, which is shown to be important for NADPH binding. During the enzymatic reaction that leads to H2O2 destruction, catalase is first oxidized to a hypervalent iron intermediate (compound 1), which is then reduced back to the resting state by a second H2O2 molecule. This ZooMAbZooMAb® 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.

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.
