Structural Info
FormulationLyophilized in sterile filtered solution of PBS with 1% CHAPS
ReconstitutionBefore 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.
StabilityThe 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.
PurityGreater than 85% as determined by SDS-PAGE and HPLC analysis
Biological ActivityThe 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 OriginUSA

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.

Stemrd的WNT-5a属于激活“非规范”途径的WNT蛋白类别。小鼠WNT-5a的预测大小是一种包含356个氨基酸残基的单体蛋白。由于糖基化作用,在非还原条件下,通过SDS-PAGE分析,它以〜45 kDa的表观分子量迁移。StemRD的产品是从小鼠细胞系表达而来,并通过不同于公开方法的专有工艺进行纯化。
