Heparan Sulfate Proteoglycan, Domain 4 (Perlecan, HSPG)
Description:
Perlecan is a major heparan sulfate proteoglycan (HSPG) found within all basement membranes and cell surfaces. Because of its strategic location and ability to store and protect growth facors, perlecan hs been stronglyimplicated in the control of tumor cell growth and metastatic behavior. Perlecan possesses angiogenic and growth promoting attributes primarily by acting as a coreceptor for basic fibroblast growth factor. Suppression of perlican causes substantial inhibition of neoplastic growth and neovasacularization. Thus, perlecan is a potent inducer of neoplasm growth and angiogaenesis in vivo and therapeutic interventions targeting this key modulator of tumor progression may improve neoplastic treatment.

Applications:
Suitable for use in Immunofluorescence and Immunohistochemistry. Not suitable for use in Western Blot. Other applications have not been tested.

Recommended Dilution:
Immunohistochemistry (Frozen and acid-alcohol fixed, paraffin embedded sections): 1-2ug/ml for 30 minutes at RT. Staining of acid-alcohol-fixed tissues requires antigen unmasking with 15,000u/ml of bovine testicular hyaluronidase in PBS, pH 7.4 for 30 minutes at 37°C
Optimal dilutions to be determined by the researcher.

Positive Control:
Tonsil

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
