Product Overview
ATF4 (Ab-245) antibody detects endogenous levels of total ATF4 protein.
This gene encodes a transcription factor that was originally identified as a widely expressed mammalian DNA binding protein that could bind a tax-responsive enhancer element in the LTR of HTLV-1. The encoded protein was also isolated and characterized as the cAMP-response element binding protein 2 (CREB-2). The protein encoded by this gene belongs to a family of DNA-binding proteins that includes the AP-1 family of transcription factors, cAMP-response element binding proteins (CREBs) and CREB-like proteins. These transcription factors share a leucine zipper region that is involved in protein-protein interactions, located C-terminal to a stretch of basic amino acids that functions as a DNA binding domain. Two alternative transcripts encoding the same protein have been described. Two pseudogenes are located on the X chromosome at q28 in a region containing a large inverted duplication.

This antibody has been validated for IHC. Always refer to the product datasheet for recommended dilution ranges and appropriate positive control samples for each application type.
Validated reactivity has been confirmed for Human. Cross-reactivity with additional species may exist based on sequence homology but has not been confirmed by the manufacturer. For unlisted species, we recommend running a preliminary validation experiment.
This antibody was raised in Rabbit. For indirect detection (WB, IHC, IF), select an anti-Rabbit secondary antibody that matches the isotype. For direct detection, check the variant selector for conjugated formats. Confirm secondary antibody compatibility before ordering.

Please refer to the storage conditions on the product label and datasheet. As a general best practice: upon receipt, aliquot into single-use volumes to minimize freeze-thaw cycling, which can progressively reduce antibody performance and lead to aggregation.
Validated reactivity covers Human samples. Performance can vary across different cell lines and tissue types depending on target antigen expression levels and epitope accessibility. We recommend verifying target expression in your specific model system using a known positive control before proceeding to experimental samples.
