GARP&Latent TGF beta Complex 蛋白, Mouse (HEK293, His)

GARP/latent TGF-b1 complexes are potent inducers of Th17 differentiation in the presence of exogenous IL-6 and inducers of Treg in the presence of IL-2. GARP&Latent TGF beta Complex Protein, Mouse (HEK293, His) is a biotinylated recombinant protein (GARP (I18-N628)&TGF-b1 (L30-S390)) produced by HEK293 cells with His tag^[1][2].

GARP/潜在 TGF-b1 复合物在外源性 IL-6 存在的情况下是 Th17 分化的有效诱导剂，在 IL-2 存在的情况下是 Treg 的诱导剂^{[1][2]GARP/LTGFβ1 复合物在新鲜移植的 Treg 上表达水平非常低，但在体外 Treg 激活后显着上调。GARP/Treg 细胞上的潜在 TGF-β1 复合物在口服耐受期间调节外周衍生 Treg 细胞的诱导[3]}

70-80 kDa

Greater than 95% as determined by Tris-Bis PAGE.

无菌粉末

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

<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.
