Human anti PTEN antibody is a recombinant Fab antibody fragment in the format Fab-Max-FH and recognizes phosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN, also known as phosphatase and tensin homolog (PTEN), MMAC1, and TEP1. The PTEN protein is a phosphatase with activity against protein and phospholipid, and acts as a potent tumor suppressor by antagonizing the PI3K/AKT pathway, whereas overexpression of this pathway drives tumorigenesis (Bermúdez Brito et al. 2015). In this way, PTEN mutations can lead to altered protein synthesis, cell cycle processes, cell growth and DNA repair (Hopkins et al. 2014). Somatic loss-of-function PTEN mutations are therefore common in many human cancers, and PTEN mutations have also been identified in autism spectrum disorder (ASD) (Rodríguez-Escudero et al. 2011). Under normal conditions, PTEN levels are tightly regulated by transciptional, post-transcriptional and post-translational methods, and small changes in PTEN levels can have dramatic effects on cellular function (Haddadi et al. 2018).

Product Details

Target Species
Western Blotting
Human anti PTEN detects a band of approximately 54 kDa in MCF-7 cell lysate
Product Form
A bivalent human recombinant Fab (lambda light chain) selected from the HuCAL® phage display library, expressed in E. coli. This Fab fragment is bivalent by dimerization of an inactive variant of the bacterial alkaline phosphatase fusion protein. The antibody is tagged with a DYKDDDDK tag and a HIS-tag (HHHHHH) at the C-terminus of the antibody heavy chain. This product is supplied as a liquid.
Prepared by affinity chromatography
Buffer Solution
Phosphate buffered saline
Preservative Stabilisers
0.01% Thiomersal
Protein was generated against the peptide HYRYSDTTDSDP (PTENaa375-388)
Approx. Protein Concentrations
IgG concentration 0.5 mg/ml

Storage Information

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
As supplied, 12 months from date of despatch
