Click here for more information.
ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

Specificity

Clone A2b1 is a ZooMAb® Mouse recombinant monoclonal antibody that specifically detects PTEN. It targets an epitope within 14 amino acids from the C-terminal region.

Immunogen

KLH-conjugated linear peptide corresponding to 14 amino acids from the C-terminal region of human PTEN.

Target description

Phosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN (UniProt: P60484; also known as Mutated in multiple advanced cancers 1, Phosphatase and tensin homolog) is encoded by the PTEN (also known as MMAC1, TEP1) gene (Gene ID: 5728) in human. PTEN, a member of the family of lipid phosphatases, contains an N-terminal phosphatase catalytic domain, a C2-domain that binds to phospholipid membranes, and a C-terminal regulatory tail. It is a dual-specific phosphatase that dephosphorylates both lipid and protein substrates. PTEN blocks the phosphatidylinositol 3-kinase/Akt signaling pathway by removing the phosphate in the 3-position on phosphoinositide-3, 4, 5-trisphosphate (PIP3). Dephosphorylation of PIP3 blocks Akt signaling. PTEN activity, stability, localization, and conformation are controlled through complex regulatory mechanisms, including the reversible phosphorylation of several serine/threonine residues in its unfolded C-terminal tail region (aa 351-403). Alternative translation of PTEN is reported to encode a 576-amino acid translational variant that is known as PTEN-Long with a 173-amino acid domain at its N-terminus followed by the classical 403 amino acids of PTEN. PTEN-Long is a membrane permeable, secreted protein that can enter other cells and acts as an antagonist of the PI3 kinase pathway. PTEN is considered a major tumor suppressor and its mutations are reported in several human tumors. Over seventy different types of PTEN mutation have been recorded in patients with Cowden syndrome. PTEN -/- mice exhibit higher levels of 3 -phosphorylated phospholipids and die during embryogenesis due to the failure of developmental apoptosis. This ZooMAbZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant mouse 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.

Reconstitution

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

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.
