The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/2000 - 1/10000. Detects a band of approximately 53 kDa (predicted molecular weight: 53 kDa).
Use at 2-5 µg/mg of lysate.
1/1000 - 1/5000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
E3 ubiquitin ligase catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins. These substrates include FILIP1, p53/TP53, CDKN1A and TERT. Keeps cells alive by suppressing p53/TP53 under normal conditions, but stimulates apoptosis by repressing CDKN1A under stress conditions. Acts as a negative regulator of telomerase. Has negative and positive effects on RNA polymerase II-dependent transcription.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma tissue labelling MKRN1 with ab72054 at 1/1000 (1µg/ml). Detection: DAB.
Western blot - Anti-MKRN1 antibody (ab72054)
All lanes : Anti-MKRN1 antibody (ab72054) at 0.1 µg/ml
Lane 1 : Whole cell lysate from HeLa cells at 50 µg Lane 2 : Whole cell lysate from HeLa cells at 15 µg Lane 3 : Whole cell lysate from HeLa cells at 5 µg Lane 4 : Whole cell lysate from 293T cells at 50 µg
Predicted band size : 53 kDa Observed band size : 53 kDa Additional bands at : 100 kDa,16 kDa,28 kDa,45 kDa. We are unsure as to the identity of these extra bands.
