  • 功能Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions. Plays a role in the reversible S-nitrosylation of cysteine residues in target proteins, and thereby contributes to the response to intracellular nitric oxide. Nitrosylates the active site Cys of CASP3 in response to nitric oxide (NO), and thereby inhibits caspase-3 activity. Induces the FOS/JUN AP-1 DNA-binding activity in ionizing radiation (IR) cells through its oxidation/reduction status and stimulates AP-1 transcriptional activity.
    ADF augments the expression of the interleukin-2 receptor TAC (IL2R/P55).
  • 序列相似性Belongs to the thioredoxin family.
    Contains 1 thioredoxin domain.
  • 翻译后修饰In the fully reduced protein, both Cys-69 and Cys-73 are nitrosylated in response to nitric oxide (NO). When two disulfide bonds are present in the protein, only Cys-73 is nitrosylated. Cys-73 can serve as donor for nitrosylation of target proteins.
    In case of infection, ubiquitinated by S.typhimurium protein slrP, leading to its degradation.
  • 细胞定位Nucleus. Cytoplasm. Secreted. Secreted by a leaderless secretory pathway. Predominantly in the cytoplasm in non irradiated cells. Radiation induces translocation of TRX from the cytoplasm to the nucleus.

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 12 kDa

    Exposure time : 30 seconds
  • ab26320 staining TRX in HLE-Be lens cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 3.7% formaldehyde, permeabilized with 0.25% Triton X-100 in PBS and blocked with 1% BSA. Samples were incubated with primary antibody (1/1500) overnight at 4°C. An Alexa Fluor® 488-conjugated Goat anti-rabbit polyclonal was used as the secondary antibody (1/1000). TRX stained in green, Mitotracker red and merging of the 2 images.

  • ab26320 staining Thioredoxin (red) in Cat urinary bladder tissue by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were blocked with 1% BSA in TBS-T for 40 minutes at room temperature and heat antigen retrieval was processed at 99°C for 15 minutes in 0.1M EDTA-NaOH buffer. Samples were incubated with primary antibody (1/100) overnight at 4°C. Nuclei stained with DAPI (blue). a = Transitional cell epithelium, b = Lamina propria mucosae, c = Muscle tunic

  • Thioredoxin / TRX was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to Thioredoxin / TRX and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab26320.

    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).

    Band: 12kDa; Thioredoxin / TRX

  • Immunofluorescent detection of Thioredoxin /TRX using antibody ab26320. Chinese Hamster Cell (Ovary cells) were fixed in formaldehyde and permeabilized in 0.1% Triton X in PBS/3% BSA. Primary antibody was incubated at 1/1000 for 1h @ 4°C in PBS containing 3% BSA.  Secondary antibody: anti-rabbit conjugated to Alexa Fluor® 568 used @ 1/300.  CHO cells co-transfected with plasmids encoding GFP and a mutated form of human thioredoxin which does not enter the nucleus, and labelled using ab26320 (1/1000) and Alexa 568 (1/300). Panel [A] demonstrates GFP immunoreactivity. [B ]thioredoxin immunoreactity; many of the same cells are immunoreactive for both GFP and thioredoxin. Panel [D] thioredoxin primary antibody was omitted, hence there is no immunoeactivity.

  • ab26320 staining Thioredoxin/TRX in Human lung tissue sections by IHC-P (Formaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 5 minutes of peroxidase block followed by 10 minutes of protein block at 20°C; antigen retrieval was heat mediated in retrieval solution. Samples were incubated with primary antibody (1/2000 in antibody diluent) for 45 minutes at 20°C. An undiluted HRP-conjugated polymer goat anti-mouse/rabbit IgG polyclonal polymer was used as the secondary antibody.

Without reduced and denatured samples, since the antibody was raised against a peptide it may not be able to recognize its epitope under the non-reduced, non-denatured conditions of the redox WB.

Since you're samples in the redox WB are non-re...

Thank you foryour reply.

I have not been able to link any of our antibodies to the one used in this article, did they suggest a catalogue number?

We have several antibodies against thioredoxin which may be of interest to you. The on...

Merci de votre intérêt pour nos anticorps. La TRX80 correspond effectivement aux 80 acides aminés N terminaux de TRX. J'ai donc cherché dans nos anticorps si nous avons un qui reconnait un épitope dans les premiers 80 acides aminés. Pou...
