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

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 80 kDa (predicted molecular weight: 69 kDa).
ICC/IF Use a concentration of 1 µg/ml.



  • All lanes : Anti-eIF4B antibody (ab38359) at 1 µg/ml

    Lane 1 : HeLa (Human epithelial carcinoma cell line) Whole Cell Lysate

    Lane 6 : SHSY-5Y (Human neuroblastoma cell line) Whole Cell Lysate

    Lysates/proteins at 10 µg per lane.

    All lanes : IRDye 680 Conjugated Goat Anti-Rabbit IgG (H+L) at 1/10000 dilution

    Performed under reducing conditions.

    Predicted band size: 69 kDa
    Observed band size: 80 kDa
    why is the actual band size different from the predicted?

  • ICC/IF image of ab38359 stained human HeLa cells. The cells were PFA fixed (10 min), permabilised in TBS-T (20 min) and incubated with the antibody (ab38359, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

Customer reviews and Q&As


Thank you very much for contacting us regarding our eIF4B antibodies. We sell these three particular antibodies because they have been derived from different areas of human eIF4B. Ab78916 is derived from human eIF4B around the phosphorylation site of serine 422 (T-G-SP-E-S). Ab66780 corresponding to a region within C terminal amino acids 505-554 and ab38359 derived from within residues 300 - 400 of Human eIF4B. If an antibody has not been tested in an assay or one a species with >85% homology, I can offer a discount off a future purchase if you buy that now, test it and submit feedback to us in the form of an Abreview. It doesn’t matter whether the Abreview is positive or negative, we would just really like to receive your feedback. The discount would be to the value of 1 free primary antibody. If you are interested in this offer Terms and Conditions of this offer can be found at: www.abcam.com/collaborationdiscount. If you are not interested in creating an abreview, I would suggest using ab78916 as it has been tested for WB, IHC and ICC-IF. Our Abpromise ensures that you can trust our products to perform as stated on the datasheets, or we will offer a replacement, credit, or refund. The Abcam Abpromise® guarantee: • 100% Scientific and Customer Support for any product you buy from Abcam or one of our authorized distributors. • We guarantee our products work in the tested species and applications stated on the datasheet. • We will replace or refund products not performing as stated on the datasheet if reported within 6 months of purchase. • We investigate any quality concerns raised by customers to ensure our catalog contains products that perform to the highest standards. Please note these conditions to our Abpromise®: • Protocol information must be provided in order for the claim to be validated. • Antibodies tested in recombinant samples only are not guaranteed for use on endogenous samples. • “Predicted to react” information on the datasheets is provided for reference only and these species are not guaranteed. • Fast Track antibodies are covered for ELISA against the immunizing peptide only. I hope this information is helpful, but please do not hesitate to contact us with further questions.
