Translation is also initiated by the function of EIF1B in regulating the activity of ribosomal subunits 43S, 48S and 40S. EIF1B enables 43S ribosomal complexes to distinguish between cognate and near-cognate initiation codons, perceiving the nucleotide content of initiation codons.\u003c\/p\u003e\n\u003cp\u003eResearch into Human EIF1B Protein supports investigations in cellular signaling and fundamental cell biology, with implications for epigenetics \u0026amp; gene regulation.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003e\u003cspan class=\"bhp-cat-pill\"\u003eE. coli (Prokaryotic)\u003c\/span\u003e\u003cspan class=\"bhp-cat-pill\"\u003eN-His\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eProduced in \u003cstrong\u003eE. coli (Prokaryotic)\u003c\/strong\u003e, yielding a high-purity non-glycosylated form suitable for structural and biochemical applications.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eN-His\u003c\/strong\u003e enables single-step affinity purification and can also serve as a handle for direct detection using anti-tag antibodies without target-specific reagents.\u003c\/p\u003e\n\u003cp\u003eExpression region: \u003cstrong\u003eMet 1-Phe113\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eProtein Specifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Weight (Calculated)\u003c\/th\u003e\n\u003ctd\u003e15.0 kDa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Weight (Observed SDS-PAGE)\u003c\/th\u003e\n\u003ctd\u003e16 kDa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePurity\u003c\/th\u003e\n\u003ctd\u003e\u0026gt; 95% as determined by reducing SDS-PAGE.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAffinity Tag\u003c\/th\u003e\n\u003ctd\u003eN-His\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eExpression System\u003c\/th\u003e\n\u003ctd\u003eE. coli (Prokaryotic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEndotoxin Level\u003c\/th\u003e\n\u003ctd\u003e\u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFormulation\u003c\/th\u003e\n\u003ctd\u003eLyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl, 500mM NaCl, pH 8.0.
