Scientific Data

Western Blot View Larger

Detection of Human MESP1 by Western Blot. Western blot shows lysates of Mouse ES cells transfected with human MESP1 untreated (-) or treated (+) with 100 ng/mL Doxycycline for overnight. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human MESP1 Monoclonal Antibody (Catalog # MAB92192) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for MESP1 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

Background: MESP1

Mesoderm posterior protein 1 (Mesp-1) is a 268 amino acids protein that in humans is encoded by the MESP1 gene. Mesp-1 was first identified in transcripts enriched in the posterior region of the mouse embryo at embryonic day E7 to E7.5. Lineage tracing in mice showed that Mesp-1 represents the earliest marker of cardiac progenitors and directs multipotential cardiovascular cell fates, patterning mesoderm into cardiac, hematopoietic, or skeletal myogenic progenitors in a context-dependent manner.
