Structural Info | |||||
Formulation | Lyophilized in sterile filtered solution of PBS with 2% 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 1 year if stored at -80 °C. Reconstituted protein is stable for at least1 month at 4 °C, but should be stored in aliquots at -80 °C forlonger term. Avoidrepeated freeze and 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 co-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 mouse WNT-5a is a monomeric protein containing 356 amino acidresidues. Due to glycosylation, itmigrates at an apparent molecular weight of ~45 kDa by SDS-PAGE analysis undernon-reducing conditions. StemRD’sproduct is expressed from a mouse cell line, and purified with a proprietaryprocess that is distinct from the published method.
