Protein PML (UniProt: P29590; also known as E3 SUMO-protein ligase PML, Promyelocytic leukemia protein, RING finger protein 71, RING-type E3 SUMO transferase PML, Tripartite motif-containing protein 19, TRIM19) is encoded by the PML (also known as MYL, PP8675, RNF71, TRIM19) gene (Gene ID: 5371) in human. PML is the eponymous and main structural component of the PML nuclear bodies (PML NBs). It is involved in a variety of cellular processes, including tumor suppression, transcriptional regulation, apoptosis, senescence, DNA damage response, and viral defense mechanisms. It has been reported that PML recognizes misfolded proteins and acts as a SUMO E3 ligase by promoting the attachment of SUMO to these substrates. PML preferentially catalyzes modification with the SUMO2/SUMO3 variants that are prone to the formation of polymeric SUMO chains. SUMO2/SUMO3 chains subsequently serve as a docking site for RNF4, which earmarks the misfolded proteins for proteasomal degradation by adding a ubiquitin tag. PML protein is localized in the nucleus and in cytoplasm. 14 different isoforms of PML have been described that are produced via alternative splicing. Isoform PML-1 is shown to shuttle between the nucleus and cytoplasm and Isoforms 2-6 are localized in the nucleus. Some isoforms, such as PLML 7 and 14 lack nuclear localization signal and are only cytosolic. Acetylation at Lys-487 is shown to be essential for its nuclear localization. Within the nucleus, most of PML is expressed in the diffuse nuclear fraction of the nucleoplasm and only a small fraction is found in the matrix-associated PML-NBs. The transfer of PML from the nucleoplasm to PML-NBs is dependent on its phosphorylation and sumoylation. The B1 box (aa 124-166) and the RING finger (aa 57-92) zinc fingers are also required for the localization in PML-NBs. PML is also observed in mitochondria-associated membranes (MAMs) that connect the endoplasmic reticulum (ER) and the mitochondria. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

KLH-conjugated linear peptide corresponding to 19 amino acids from the N-terminal region of human Promyelocytic leukemia protein (PML).

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
