靶标

  • 相关性

    HCV (Hepatitis C Virus) viral core protein forms the internal viral coat that encapsidates the genomic RNA and is enveloped in a host cell-derived lipid membrane. The hepatitis C virus (HCV) core protein represents the first 177 amino acids of the viral precursor polyprotein and is cotranslationally inserted into the membrane of the endoplasmic reticulum. The N terminus of the core protein is involved in transcriptional repression. There are over 20 different subtypes of Hepatitis C Virus; HCV type 1b is mostly found in Europe and Asia. The prevalence of HCV type 1b infection has recently decreased, although it still accounts for most HCV-related cirrhosis and hepatocellular carcinoma. High HCV viremia levels and HCV genotype type 1b are independent predictors for poor response to interferon-alpha therapy. HCV core protein is among the most conserved proteins in HCV and is known to induce sensitization of cytotoxic T lymphocytes (CTL). Therefore, it is a prime candidate for a component of a potential HCV vaccine.

Cells were fixed with paraformaldehyde, permeabilized with Triton X-100 and blocked with 1% BSA for 30 minutes at 37°C. Samples were incubated with primary antibody (1/200 in PBS + 1% BSA) for 1 hour at 37°C. An undiluted Alexa Fluor® 647-conjugated Goat anti-mouse IgG monoclonal was used as the secondary antibody.

    Answer

    Thank you for confirming the details of this product.

    I am pleased to provide thetesting protocol for ELISA using this antibody which I have copied below. Please note, this is a guideline only and may require some individual optimization.

    While we do not recommend an ELISA specific dilution for this antibody,a usefulstandard starting point for recommendations for ELISA antibody concentrations is 1-10ug/ml for coating and 1-5ug/ml for detection.

    I hope the following article may also be helpful to you:

    I am sorry to confirm that the cut off point has not been determiened. Calculation of the results and statistics will depend on what you require. I can recommend to review further details in the instructions for the platereader software regarding data analysis. I am sorry we have no more specific information to provide.

    I hope this will be helpful. If you have any further questions, please do not hesitate to contact me.

    General ELISA Protocol

    1. Bind Antigen to Microplate

    a. Dispense 1-5 mg antigen in PBS into each well.
    b. Cover the plate with parafilm and place in the refrigerator overnight.
    c. Remove and discard antigen solution from plate.

    2. Blocking and Primary Antibody Incubation

    a. Block each well in the entire microplate by adding 200 ml of 2.5 mg/ml BSA in PBS to each well.
    b. Allow plate to stand at room temperature for 2 hours.
    c. Remove and discard blocking solution from plate.
    d. Add the appropriate amount of primary antibody to each well and incubate at room temperature for 1 hour.
    e. Remove and discard incubation solution from plate.
    f. Wash each well using TBST (TBS containing 0.1% Tween20). Do NOT cross-contaminate wells.
    g. Repeat washing step for a total of 5 washes.

    3. Secondary Incubation and Detection

    a. Add appropriate amount of secondary antibody solution wells and incubate at room temperature for 1 hour.
    b. Remove and discard secondary antibody solution from plate.
    c. Wash each well using TBST (TBS containing 0.1% Tween20). Do NOT cross-contaminate wells.
    d. Repeat washing step for a total of 5 washes.
    e. Add the appropriate detection reagent, incubate, and stop the color development according to manufacturer’s recommendations.
    f. Read the plate according to manufacturer’s recommendations.

    Question

    will this antibody (ab2740) recognize genotype 1a virus? Thanks in advance for your help!

    Answer

    It is not known. From epitope mapping it has been shown to be directed against aa 21-40 of the HCV core region. I would suggest seeing how conserved this sequence is in 1a.
