Structural Info | |||||
Formulation | Lyophilized in sterile filtered solution of PBS with 1% CHAPS | ||||
Reconstitution | Before reconstitution, werecommend a brief spin to drive down any material dislodged from the bottom ofthe tube. The lyophilized protein shouldbe reconstituted in sterile H2O to a concentration of 100 ng/uL. Because of the hydrophobic nature of thisprotein, further dilutions should be made in buffer or medium containingcarrier proteins, such as albumin or serum. | ||||
Stability | The lyophilized protein isstable for at least 6 months if stored at -80 °C. Reconstituted protein is stable for at least 2weeks at 4 °C, but should be stored in aliquots at -80 °C forlonger term. Avoidrepeated freeze/thaw. | ||||
Purity | Greater than 85% as determined by SDS-PAGE and HPLC analysis | ||||
Biological Activity | The activity was determined by using a TCF reporter gene assay in 293 cells transfected with Frizzled-4 and LRP-5.WNT-5a activates (instead of inhibits) the TCF reporter gene in this assay. | ||||
Country of Origin | USA |
WNT-5a belongs to the class of WNT proteins thatactivate the “non-canonical” pathway. Thepredicted size of human WNT-5a is a monomeric protein containing 357 amino acidresidues. Due to glycosylation, itmigrates at an apparent molecular weight of ~45 kDa on SDS-PAGE undernon-reducing conditions. StemRD’sproduct is expressed from a human cell line in animal-free medium, and purifiedwith a proprietary process that is distinct from the published method.
