TREX1 antibody will not cross-react with the related protein TREX2.

TREX1 Antibody is affinity chromatography purified via peptide column.

Liquid

1 mg/mL (lot specific)

TREX1 antibody can be stored at 4 degree C for three months and -20 degree C, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.

Small volumes of anti-TREX1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

TREX1 Antibody: Trex1 is the major human 3' to 5' exonuclease which is required for checkpoint signaling after DNA damage. It is ubiquitously expressed, binds to single stranded DNA coated with replication protein A that accumulates at sites of DNA damage and recruits the ataxia telangiectasia and Rad3 related protein (ATR), a checkpoint kinase, to sites of DNA damage and replication stress. Trex1 is required for ATR expression. This gene uses two different open reading frames. The upstream ORF encodes proteins which interact with ATR and localize to intranuclear foci induced by DNA damage and are essential components of the DNA damage checkpoint. The downstream ORF encodes proteins with 3' to 5' exonuclease activity and may be a subunit of human DNA polymerase III. Multiple transcript variants encoding different isoforms have been found. Mutations in this gene result in Aicardi-Goutieres syndrome, chilblain lupus, and Cree encephalitis.

ELISA (EIA), Western Blot (WB), Immunohistochemistry (IHC), Immunofluorescence (IF)

TREX1 antibody can be used for detection of TREX1 by Western blot at 0.5 and 1 mug/mL. Antibody can also be used for immunohistochemistry starting at 2.5 mug/mL. For immunofluorescence start at 20 mug/mL.

TREX1_HUMAN

This gene encodes a nuclear protein with 3' exonuclease activity. The encoded protein may play a role in DNA repair and serve as a proofreading function for DNA polymerase. Mutations in this gene result in Aicardi-Goutieres syndrome, chilblain lupus, Cree encephalitis, and other diseases of the immune system. Alternative splicing results in multiple transcript variants.

TREX1: the major 3' DNA exonuclease in mammalian cells. Normally associates with the endoplasmic reticulum (ER). Translocates to the nucleus at S phase after DNA damage by gamma-irradiation or hydroxyurea. Trex1-deficient cells show defective G1/S transition, with single-stranded DNA molecules persisting after S phase and accumulating in the ER. Degrades ssDNA. Prevents chronic checkpoint activation and inappropriate immune activation. Mutations cause Aicardi-Goutieres syndrome, an autoimmune disorder. Trex1a(-/-) mice have autoinflammatory responses. The gene for this protein is either identical to or adjacent to that of ATRIP. Some of the mRNAs that encode TREX1 also encode ATRIP in another reading frame. Three alternatively spliced human isoforms have been reported.
