靶标

  • 相关性

    HCV is a positive, single-stranded RNA virus in the Flaviviridae family. The genome is approximately 10,000 nucleotides and encodes a single polyprotein of about 3,000 amino acids. The polyprotein is processed by host cell and viral proteases into three major structural proteins including NS3, and several non-structural proteins necessary for viral replication. The NS3 part of the polyprotein displays three enzymatic activities: serine protease, NTPase and RNA helicase. The NS3 serine proteinase (NS3P) is a non-structural hepatitis C protein responsible for proteolytic processing of other non-structural proteins; because of this, it is also the most extensively studied protein of the Hepatitis C genome. It is responsible for proteolytic processing of the entire downstream region of the HC polyprotein, catalyzing cleavage at the NS3/NS4a, NS4a/NS4b, NS4b/NS5a, and NS5a/NS5b sites to release the mature NS3, NS4a, NS4b, NS5a, and NS5b proteins.For proper function, NS3 requires NS4a as a cofactor, but, interestingly enough, NS3 also cleaves the NS4a protein. The molecular weight of the monomer NS3P is 70 kDa.

    Question

    Dear Sir/Madam,

    I have a question regarding storage of two antibodies bought from you,a b13830 and ab13833. Due to a misunderstanding, the antibodies have been stored at +4 C, even though the product sheet recommends storing at –20 C. The antibodies have been stored at +4 C approximately two weeks. Do you know if this will affect the products negatively?

    Yours sincerely,

    Answer

    Thank you for your message.

    Reviewing the recommended storage details for these antibodies, I can suggest they should not be significantly affected by short term storage for a week or two at +4oC. However, I would recommend to aliquot and freeze them as soon as possible.

    We would recommend that products are stored as recommended on the datasheet as soon as they are delivered. This will ensure the product remains stable and that we can continue to provide our guarantee.

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

    Question

    Hi,   I am interested in the hepatitis C anti-NS3 antibody for WB. I would like to check the expression condition of the NS3 protein using the antibody, especially its helicase domain.  Would you suggest any antibody fit for this purpose? I have rabbit/mouse HRP secondary antibody. Thanks.   Yi

    Answer

    Thank you for your enquiry. I am sorry it has taken some time to request the immunogen seuqences from our sources and review these for you, thank you for your patience. I can confirm the following mouse Hepatitis C Virus NS3 antibodies have been tested in wesern blot and should detect the helicase domain. I can recommend to review the online datasheets for further information: ab13830 Hepatitis C Virus NS3 antibody [H23] Mouse monoclonal Applications: ELISA, IHC-P, WB The immunogen for this mab was of the genotype 1b, the exact sequence is unknown. The epitope has been mapped to the helicase domain (between aa positions 1350 and1500). Click here (or use the following: https://www.abcam.com/Hepatitis-C-Virus-NS3-antibody-H23-ab13830.html). ab65407 Hepatitis C Virus NS3 antibody [8 G-2] Mouse monoclonal Applications: ELISA, ICC/IF, IHC-P, WB The epitope has been mapped between amino acid positions 1340 and 1480 The antibody includes and recognises the helicase domain. Click here (or use the following: https://www.abcam.com/Hepatitis-C-Virus-NS3-antibody-8-G-2-ab65407.html). I am still waiting for confirmation of the immunogen from several more antibodies. I will contact you again if I have any further information that any will detect the helicase domain. I hope this will be helpful to you. Should you have any further questions, please do not hesitate to contact us.

    Question

    here is the scan of the blot. there is a good band but unfortunately it shows up in the negative control which is the 20.5 and does not show up in the positive control using NS3 protein only. let me know what you think.

    Read More
    Answer

    Thank you for sending me the image of your blot. So, you have no bands (just some background) in the NS3 recombinant protein lane, and the same pattern of bands in the other lanes, including the negative control. Just to make sure, do you know that your secondary antibody is working properly? Also, have you tried in the past another Hepatitis C Virus antigen antibody with these samples?

Hi I actually purchased this antibody the hepatitis C virus antigen and tested the Western Blot specificity using a control containing HCV NS3 positive and a negative control and did not receive a specific band in the correct size. I performed the WB at both the suggested dilution of antibody 1:1000 and at 1:500. neither blot worked. There was proper transfer of protein but too many non-specific bands and non at the specific size. Is there another antibody that I can get as a replacement or a refund?? please let me know asap, I can send you the blot as an attachment if you want to see.

    Answer

    Thank you for your message and I'm sorry to hear that you are experiencing difficulty with ab13830. It would be helpful if you could send me an image of the blot. You mention no signal but then mention non-specific bands. How strong are these bands? What are you seeing in your negative control lanes? At this point I would like to make a few suggestions that will hopefully help you out. Try incubating with the primary at a dilution of 1:1000 overnight at 4C. Also, you mention that you are seeing non-specific bands; make sure to run a secondary only control (no primary antibody) to ensure that these bands are not due to your secondary antibody. Thanks, and I look forward to hearing from you.
