Our Abpromise guarantee covers the use of ab19048 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
ELISA Use at an assay dependent concentration.
IHC-P Use at an assay dependent concentration.

Immunoperoxidase-avidin-biotin (ABC) assay for formalin-fixed paraffin embedded tissue section using diluted MAb. The dilution of MAb should be tested based on your working system.

WB Use a concentration of 0.5 µg/ml.

Use at a concentration of 0.5 µg/ml to detect 0.5 µg/lane of synthetic NS4 peptide and 0.1 µg/lane recombinant chimeric HCV polyprotein.

    NS4 A/B are two of the seven nonstructural (NS) proteins making up the HCV polyprotein. The NS proteins recruit the viral genome into an RNA replication complex, which is associated with rearranged cytoplasmic membranes. NS4A acts as a cofactor with the NS3 serine protease and stabilizes its folding. The NS3-NS4A complex is essential for the activation of the latter and allows membrane anchorage of NS3. 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. HCV is responsible for a large proportion of worldwide chronic viral hepatitides. Most of these infections develop into chronic hepatitis, which often progresses to liver cirrhosis and hepatocellular carcinoma. At present, (unlike hepatitis A and B), there is no vaccine to prevent hepatitis C infection. The hepatitis C virus (HCV) nonstructural protein 4B (NS4B) is a relatively hydrophobic 27-kDa protein. The 4A protein has a molecular weight of 6 kDa.

Thank you for your enquiry. I was able to receive two IHC pictures of ab19048 from the researcher who tested it in IHC. Please find the two images on the datasheet. The tissue section shown in both was liver cancer section, one picture was at high ...
