Western blot analysis of extracts from various cell lines using PML (E5R8T) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower). In agreement with RNA-seq studies, AN3-CA cells express very low levels of PML protein.
Western blot analysis of MDA-MB-231 cells expressing inducible HA-tagged PML protein (MDA-MB-231 HA-PML), either uninduced (-) or induced with doxycycline (50 ng/ml, 6 d; +), using PML (E5R8T) Rabbit mAb (upper), HA-Tag (C29F4) Rabbit mAb #3724 (middle) or β-Actin (D6A8) Rabbit mAb #8457 (lower). As expected, doxycycline induction increased the expression level of PML protein. Cells were kindly provided by Dr. Arkaitz Carracedo, Natalia Martin, Laura Bozal and Amaia Ercilla.
Western blot analysis of extracts from 293T cells, mock transfected (-) or transfected (+) with Myc/DDK-tagged cDNA expression constructs encoding full-length human PML protein (hPML-Myc/DDK) or full-length mouse PML protein (mPML-Myc/DDK), using PML (E5R8T) Rabbit mAb (upper) or DYKDDDDK Tag (D6W5B) Rabbit mAb #14793 (lower). As shown, PML (E5R8T) Rabbit mAb detects overexpressed human PML protein (hPML-Myc/DDK), but not mouse PML protein (mPML-Myc/DDK).

PML (E5R8T) Rabbit mAb recognizes endogenous levels of total PML protein.
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro364 of human PML protein.
Promyelocytic leukemia protein (PML) functions via its association with PML bodies in the nucleus (1). PML bodies are dynamic protein aggregates that are interspersed between chromatin in the nuclei of most mammalian cells. The PML protein acts as a scaffold in PML bodies to recruit other proteins, a process regulated by post-translational modifications, such as sumoylation. PML bodies function to regulate a large number of cellular processes, such as tumor suppression, transcriptional regulation, apoptosis, senescence, DNA damage response, and viral defense (1). The chromosomal translocation t(15;17)(q21;q21) involving the fusion of PML and RARalpha is found in acute promyelocytic leukemia (APL), while a second translocation t(9;15)(p13;q24) involving the fusion of PML and PAX5 was found in acute lymphoblastic leukemia (ALL) (2-6). In addition, PML is frequently inactivated or downregulated in cancer.
