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 4H1 is a ZooMAb® mouse recombinant monoclonal antibody that specifically detects LINE-1 retrotransposable element ORF1 protein. It targets an epitope within 10 amino acids from the N-terminal region.

Immunogen

A linear peptide corresponding to 10 amino acids from the N-terminal region of human LINE-1 ORF1 protein.

Application

Quality Control Testing

Evaluated by Western Blotting in MCF-7 cell lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected LINE-1 ORF1p in MCF-7 cell lysate.

Tested Applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected LINE-1 ORF1p in NTERA-2 cell lysate.

Flow Cytometry Analysis: 0.1 μg from a representative lot detected LINE-1 ORF1p in one million MCF-7 cells.

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected LINE-1 ORF1p in MCF-7 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-LINE-1 ORF1p, clone 4H1 ZooMAb®, Cat. No. ZMS1066, is a recombinant Mouse monoclonal antibody that specifically targets LINE-1 ORF1p and is tested for use in Flow Cytometry, Immunocytochemistry, and Western Blotting.

Target description

LINE-1 retrotransposable element ORF1 protein (UniProt: Q9UN81; also known L1ORF1p, LINE retrotransposable element 1, LINE1 retrotransposable element 1) is encoded by the LIRE1 (also known as LRE1) gene in human. LINE1-ORF 1P is a homotrimeric protein of the transposase 22 family that can also form larger homooligomers. It is mainly a cytoplasmic protein and is enriched in stress granules, but may also be detected in the nucleolus. It contains a coiled coil domain that mediates its homotrimerization. Its RNA recognition motif (RRM) (aa 157-252) in the C-terminal domain are required for its proper RNA-binding activity. LINE1-ORF 1P serves as a nucleic acid-binding protein that is essential for retrotransposition of LINE-1 elements in the genome. It is also reported to function as a nucleic acid chaperone binding its own transcript and therefore preferentially mobilizing the transcript from which they are encoded. Retrotransposition is a shown to be a complex process that involves transcription of the LINE1, transport of its RNA to the cytoplasm, translation of the bicistronic RNA, formation of a ribonucleoprotein particle, its re-import to the nucleus and then target-primed reverse transcription at the integration site. LINE1-ORF 1P expression is consistently detected in p53 mutant tumors, but, little or no expression is detected in Wilms tumors that were normal for p53. 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 mouse monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. 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.
