SOS1, FLAG-Tag, Avi-Tag, Biotin-Labeled Recombinant
Human Son of sevenless homolog 1 (SOS1), also known as guanine nucleotide exchange factor 1 (GEF1), encompassing amino acids 594-1049. This construct contains an N-terminal FLAG-tag and a C-terminal Avi-tag™. The recombinant protein was affinity purified and enzymatically biotinylated using Avi-Tag™ technology. Biotinylation is confirmed to be ≥90%.
≥85%
Aqueous buffer solution
40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 20% glycerol, 3 mM DTT, and 80 µg/ml FLAG peptide
