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 (Biotinylated, HEK293, His-Avi) is a biotinylated recombinant protein (GARP (I18-N628)&TGF-b1 (L30-S390)) produced by HEK293 cells with His-Avi tag[1][2].
