  SALL4 is an important transcription factor that supports the expansion of hematopoietic stem cells. SALL4 expression is also deregulated in several types of leukemia. Recent studies reveal that SALL4B, a major isoform of SALL4, is heavily modified by post-translational mechanisms and these modifications are critical for their stability, subcellular localization, and transcriptional activities. Given the importance of SALL4B in supporting stem cell selfrenewal and expansion, we optimized a large scale expression and purification process to obtain SALL4B using the baculovirus expression vector system. Recombinant TAT-SALL4B was efficiently purified by nickel affinity chromatography under native conditions. Immuno-blotting confirmed that recombinant SALL4B was highly expressed and purified. As the first step to test the biological activity of purified TA.. View More»
