Intracellular Flow Cytometry analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labeling NELFe with Purified ab170104 at 1/300 dilution (1μg/ml) (red). Cells were fixed with 4% Paraformaldehyde. 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 (ab170104).

Immunocytochemistry/ Immunofluorescence analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labeling NELFe with Purified ab170104 at 1 : 500 dilution (0.5 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 nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Biological function summary
NELFe influences gene expression by controlling the pausing of RNA Polymerase II which impacts the timing and localization of transcription. NELFe operates within a larger complex known as the Negative Elongation Factor complex that consists of NELF-A (NELFe) NELF-B NELF-C/D and NELF-E. This complex enables precise regulation of transcriptional pausing and subsequent release when appropriate signals arrive. The coordinated action of this complex ensures proper gene expression profiles necessary for development and cell differentiation.
Pathways
NELFe fits prominently in the transcription regulation pathway where it controls RNA Polymerase II pausing and release. NELFe interacts with the protein P-TEFb (Positive Transcription Elongation Factor b) which phosphorylates NELF complex components to release the pause allowing elongation. Another significant pathway involves NELFe in the regulation of heat shock genes where the heat shock factor 1 (HSF1) modulates the transcriptional pause release in response to stress showing NELFe's role in cellular stress responses.
