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

应用 Ab评论 说明
WB Use a concentration of 1 µg/ml. Detects a band of approximately 27 kDa (predicted molecular weight: 22 kDa).
IHC-P Use a concentration of 0.75 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC/IF Use a concentration of 5 µg/ml.

  • ICC/IF image of ab84258 stained HepG2 cells. The cells were 4% formaldehyde (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab84258, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • All lanes : Anti-Interferon beta antibody (Biotin) (ab84258) at 1 µg/ml

    Lane 1 : Human liver tissue lysate - total protein (ab29889)
    Lane 2 : Human spleen tissue lysate - total protein (ab29699)
    Lane 3 : Human kidney tissue lysate - total protein (ab30203)

    Lysates/proteins at 10 µg per lane.

    All lanes : 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: 22 kDa
    Observed band size: 27 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 100 kDa, 46 kDa, 55 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 16 minutes

    The Interferon Beta protein sequence contains both a phosphorylation and a glycosylation site (Swissprot). Post-translation modifications could account for the migration of the band at a higher molecular weight than predicted.
  • Immunohistochemical analysis of formalin-fixed, paraffin-embedded Human normal placenta, staining Interferon beta with ab84258 at 0.75 µg/ml. An HRP-labeled polymer detection system was used with a DAB chromogen. Heat induced antigen retrieval with a pH 6.0 sodium citrate buffer is recommended.

Thank you for your reply.

I do understand your concerns. It may be that you would want to run a western blot with this product to ensure that it is picking up IFN from your cells, it would them be possible to run a purified protein as control...

Thank you very much for your interest in ab84258.

Unfortunately the sequence homology between he human and mouse forms of IFNB is very low (47%). We would not be confident that this product would work in mouse.

We do have another pro...

Thank you for contacting us.

I think these two antibodies will work together in a sandwich ELISA, but we have not tested them together. You will need to test a few different dilutions to achieve the optimal signal with the least background. ...

Thank you for contacting Abcam. I have heard back from the lab and they have told me that the biotin is covalently coupled to primary amines (lysines) of the immunoglobulin and not to either the N or C terminal. If there is anything else I can help you...
