Research Use Only
For Research Use Only. Not for use in diagnostic procedures.
Sequence Length
E Coli
Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
The protein was lyophilized with 2mM Tris pH-7.4.
Sterile Filtered White lyophilized (freeze-dried) powder.
It is recommended to reconstitute the PEX in sterile 18M Omega -cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
The bioactivity was measured by HMEC cell line, PEX can inhibit the transmembrane activity of HMEC under the stimulation of VEGF.
Preparation and Storage
Lyophilized PEX although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution PEX should be stored at 4 degree C between 2-7 days and for future use below -18 degree C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Other Notes
Small volumes of PEX recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Description: PEX Human Recombinant is expressed as inclusion bodies in E Coli having a molecular mass of 28,453 Dalton and subsequently refolded in vitro to get biological activity.

Introduction: Recombinant Human PEX (C-terminal hemopexin-like domain of MMP-2) is a noncatalytic Metalloproteinase Fragment with Integrin Binding Activity and can inhibit cell associated collagenolytic activity both in vitro and in vivo. Moreover, PEX can block angiogenesis and tumor growth in vivo, providing a potentially novel therapeutic approach for diseases associated with neovascularization. The appearance of PEX at sites of neovascularization may not only control normal angiogenesis, but when administered in sufficient quantities, may provide a naturally-occurring therapeutic inhibitor of diseases associated with angiogenesis. PEX mediates interaction with inhibitors and the cell surface, and is vital for activation. PEX is composed of 4 sub-domains arranged as a 4-bladed propeller. PEX, which interferes with the cell membrane activation of MMP-2, reduced Rac1- promoted cell invasiveness as observed by collagen invasion assay. It has also been described that PEX prevents binding of MMP-2 to the integrin avb3.

NCBI Summary for PEX
The protein encoded by this gene is a transmembrane endopeptidase that belongs to the type II integral membrane zinc-dependent endopeptidase family. The protein is thought to be involved in bone and dentin mineralization and renal phosphate reabsorption. Mutations in this gene cause X-linked hypophosphatemic rickets. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
UniProt Comments for PEX
PHEX: Probably involved in bone and dentin mineralization and renal phosphate reabsorption. Defects in PHEX are a cause of hypophosphatemic rickets, X-linked dominant (XLHR). XLHR is an X-linked dominant disorder characterized by impaired phosphate uptake in the kidney, which is likely to be caused by abnormal regulation of sodium phosphate cotransport in the proximal tubules. Clinical manifestations include skeletal deformities, growth failure, craniosynostosis, paravertebral calcifications, pseudofractures in lower extremities, and muscular hypotonia with onset in early childhood. X-linked hypophosphatemic rickets is the most common form of hypophosphatemia with an incidence of 1 in 20000. Belongs to the peptidase M13 family.
