General notes
ab246346 is the carrier-free version of ab33768.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free production
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

Target
-
Function
Its translation stimulation activity is repressed by binding to the complex CYFIP1-FMR1 (By similarity). Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures. Component of the CYFIP1-EIF4E-FMR1 complex which binds to the mRNA cap and mediates translational repression. In the CYFIP1-EIF4E-FMR1 complex this subunit mediates the binding to the mRNA cap. -
Sequence similarities
Belongs to the eukaryotic initiation factor 4E family. -
Post-translational
modificationsPhosphorylation increases the ability of the protein to bind to mRNA caps and to form the eIF4F complex. - Information by UniProt

eIF4E was immunoprecipitated from 10 µg NIH/3T3 (Mouse embryonic fibroblast) whole cell lysate with ab33768 at a 1/30 dilution. Western blot was performed from the immunoprecipitate using ab33768 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/1000 dilution.
Lane 1: NIH/3T3 (Mouse embryonic fibroblast) whole cell lysate 10 µg (Input).
Lane 2: ab33768 IP in NIH/3T3 whole cell lysate.
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab33768 in NIH/3T3 whole cell lysate.Blocking/Dilution buffer: 5% NFDM/TBST.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab33768).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human ovarian cancer tissue labelling eIF4E with ab33768 at a dilution of 1/500. Antigen retrieval was performed ab93684, Tris/EDTA buffer, pH 9. A ready to use goat anti-rabbit IgG H&L (HRP Polymer) was used as the secondary antibody. Counter stained with Hematoxylin.

Immunocytochemistry/ Immunofluorescence analysis of RAW 264.7 (Mouse Abelson murine leukemia virus-induced tumor macrophage) cells labeling eIF4E with Purified ab33768 at 1/50 (10 µg/mL). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1/200 (2.5 µg/mL). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1/1000 (2 µg/mL) dilution. DAPI (blue) was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab33768). -
Intracellular Flow Cytometry analysis of HEK-293 (Human embryonickidney epithelial cell) cells labeling eIF4E with Purified ab33768 at 1/50 dilution (10 µg/mL) (Red). Cells were fixed with 4% Paraformaldehyde and permeabilised with 90% Methanol. A Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) secondary antibody was used at 1/2000. Isotype control - Rabbit monoclonal IgG (Black). Unlabeled control - Cell without incubation with primary antibody and secondary antibody (Blue). This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab33768).
