Our Abpromise guarantee covers the use of ab22850 in the following tested applications.

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 - 2 µg/ml. Detects a band of approximately 40 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use at an assay dependent concentration.


  • RelevanceCCRN4L is highly similar to Nocturnin, a gene identified as a circadian clock regulated gene in Xenopus laevis. This protein and Nocturnin protein share similarity with the C terminal domain of a yeast transcription factor, carbon catabolite repression 4 (CCR4). The mRNA abundance of a similar gene in mouse has been shown to exhibit circadian rhythmicity, which suggests a role for this protein in clock function or as a circadian clock effector.

    • CCR4 carbon catabolite repression 4 like (S. cerevisiae) antibody
    • CCR4 protein homolog antibody
    • CCRN4L antibody
