几丁质酶样蛋白 3/YM1 蛋白起到凝集素的作用,对含有游离氨基的糖类(包括葡萄糖胺或半乳糖胺)具有显着的亲和力。与单糖或二糖相比,其对低聚糖的结合亲和力要强得多。此外,几丁质酶样蛋白 3/YM1 与几丁质和肝素结合。虽然它表现出弱己糖胺酶活性,但它不具有几丁质酶活性。除了其酶促功能外,该蛋白还对 T 淋巴细胞、骨髓细胞和嗜酸性粒细胞表现出趋化活性,表明其可能参与炎症和过敏过程。

1. 分子特征与表达
生物活性
Measured by the ability of the immobilized protein to support the adhesion of FaDu human squamous cell carcinoma cells. When 5 x 10^4 cells per well are added to rmCHI3- L1 coated plate, cell adhesion is enhanced in a dose dependent manner after 30 minutes at 37 °C. The ED50 for this effect is 0.8-3.2 μg/mL. Optimal concentrations should be determined by each laboratory for each application.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
描述:
Recombinant Mouse Mouse Chitinase 3-like 1 Protein is produced by 293F expression system. The target protein is expressed with sequence (Tyr22-Ala381) of Mouse Mouse Chitinase 3-like 1 (Accession Q61362) fused with a C-His.
储存:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
未开盖的干粉蛋白在 -20°C至-80°C可保存12个月;
复溶之后,蛋白溶液在-20°C及以下可保存3个月,在2-8℃可保存1周。
复溶:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底,如果粉末浮起,开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL(请注意蛋白复溶浓度不能低于0.1 mg/mL),室温平衡5-10 min保证充分溶解,复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存,建议复溶时添加载体蛋白或者稳定剂(如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖),同时将复溶后的蛋白溶液按照需求进行分装,储存于-20°C至-80°C,随取随用,避免反复冻融。
