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 2.5 µg/ml. Predicted molecular weight: 61 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 4 - 8 µg/ml.


  • Relevance

    SLC38A4 is found predominantly in liver and transports both cationic and neutral amino acids. The transport of cationic amino acids by SLC38A4 is Na+ and pH independent, while the transport of neutral amino acids is Na+ and pH dependent. It has a broad specificity, with a preference for Ala, followed by His, Cys, Asn, Ser, Gly, Val, Thr, Gln and Met.

Customer reviews and Q&As


Unfortunately, at this time, the only data our lab has is the western blot and IHC data with human samples. We have not conducted additional experiments to address why the staining seems to be mainly cytoplasmic. Additionally, from the 14aa peptide used to raise this antibody, the only human protein that it is 100% homologous to is the SLC38A4 (http://www.uniprot.org/uniprot/Q969I6).

Due to a high sequence homology of 86% between the immunogen used and the mouse protein, we have predicted that this antibody will work in mouse however, we have not tested this and therefore, cannot guarantee this. If you would like to test this product in mouse, we could offer you a testing discount.
