XCL1 蛋白, Rat (His)

XCL1 protein attracts lymphocytes but not monocytes or neutrophils. It plays a crucial role in accumulating dendritic cells in the thymus medulla and contributes to regulatory T cell development, establishing self-tolerance. XCL1 Protein, Rat (His) is the recombinant rat-derived XCL1 protein, expressed by E. coli , with N-6*His labeled tag. The total length of XCL1 Protein, Rat (His) is 93 a.a., with molecular weight of ~13 kDa.

XCL1 蛋白表现出特异性针对淋巴细胞的趋化活性，但不吸引单核细胞或中性粒细胞。在胸腺中，它在介导髓质树突状细胞的积累中发挥着至关重要的作用，并有助于调节性T细胞的发育，从而在建立自我耐受性方面发挥着至关重要的作用。

Measured by its ability to chemoattract Jurkat cells. The ED₅₀ this effect is 27.03 ng/mL, corresponding to a specific activity is 3.70×10⁴ units/mg.

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 50 mM Tris-HCL, 300 mM NaCl, 200 mM arginine, pH 8.0.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
