| 背景描述 | Wnt3a is a secreted glycoprotein that activates the canonical Wnt/β-catenin signaling pathway, playing a crucial role in embryonic development, tissue homeostasis, and injury repair. However, its experimental application is hindered by poor solubility and cross-reactivity with multiple Frizzled receptors. To address these challenges, engineered Wnt3a surrogate proteins have been developed. These surrogates are water-soluble and designed to specifically bind to targeted Frizzled receptors, effectively mimicking natural Wnt3a activity with enhanced precision. This specificity and improved solubility make Wnt3a surrogates valuable tools in research areas such as organoid culture, stem cell maintenance, and studies of developmental biology. |

| 产品形式 | The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 7.4. If you have any concerns or special requirements, please confirm with us. |
| 产品应用 | Cell Culture |
| 储存 | Lyophilized protein: Store at -20°C for 1 year. After reconstitution: · Store at 2°C to 8°C for up to 1 week. · For extended storage (beyond 1 week), dilute the reconstituted protein in a buffer containing a carrier protein or stabilizer (e.g., 0.1% BSA, 10% FBS, 5% HSA, or 5% trehalose solution). The final concentration is not less than 10 μg/ml. Prepare aliquots (≥20 μl) and store at -20°C or -80°C for 3 to 6 months. Avoid repeated freeze-thaw cycles. |
