Specifications Synonyms LAP; GARP;LRRC32; LRRC32&TGF-beta 1 Source Biotinylated Rat GARP&Latent TGF Beta 1 Complex Protein is expressed from HEK293 with His tag and Avi Tag at the C-Terminus. It contains Ile18-Asn628(GARP)&Leu30-Arg278(Latent TGF Beta 1).[Accession | D3ZVD5(GARP)&P17246(Latent TGF Beta 1)] Molecular Weight The protein has a predicted MW of 69.80 kDa (GARP)&41.28 kDa (Latent TGF beta 1). Due to glycosylation, the protein migrates to 70-80 kDa (GARP)&42-48 kDa&13 kDa (Latent TGF beta 1) based on SDS-PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity ELISA Data: mmobilized Human ITGAV&ITGB6, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Rat GARP&Latent TGF Beta 1 Complex, His Tag with the EC50 of 0.4μg/ml determined by ELISA. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage The product should be stored at -25~-15℃ for 1 year from the date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 -6 months, -85~-65℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
