Characteristics Islet-1 is a LIM-homeodomain transcription factor important for motor neuron differentiation and the formation of islet cells in the pancreas. Various heart cell types, such as cardiac muscle, the conduction system and endothelial cells in multiple heart tissue compartments during cardiogenesis, have been found to originate from Islet-1-positive cardiac precursor cells. Moreover, Islet-1-positive cells from differentiated human embryonic stem cell lines were found to be capable of self-renewal and expansion and could differentiate into the three major cell types of the heart. Western blot analyses of lysates from transfected cells demonstrate that the Q11-465 monoclonal antibody reacts with human Islet-1 (ISL-1, ISL1) and Islet-2 (ISL-2, ISL2), similar to the 4D5 clone (Tsuchida et al, 1994). Cross-reactivity with mouse Islet is also observed. TOP LEFT: Western Blot analysis of Islet-1 in mouse pancreatic tumor (insulinoma). Lysate from Beta-TC-6 cells (ATCC CRL-11506™) was probed with Purified Mouse anti-Islet-1 monoclonal antibody at titrations of 0.5 (lane 1), 0.25 (lane 2), and 0.125 μg/mL (lane 3). Islet-1 is identified as a band of ~45-50 kDa. TOP RIGHT: Immunohistochemical staining of human Islet-1. Following antigen retrieval with BD Retrievagen A buffer (Cat. No. 550524), formalin-fixed paraffin-embedded human pancreas sections were stained with either purified mouse IgG1, κ Isotype control (Cat. No.550878, top panel) or Purified Mouse Anti-Human Islet-1 (Cat. No.562546, bottom panel). A three-step staining procedure that employs Biotin Goat Anti-Mouse Ig secondary antibody (Cat. No. 550337), Streptavidin HRP (Cat. No. 550946), and DAB substrate kit (Cat. No. 550880) was used. As shown in the figure, the lslet-1 staining is mainly nuclear in the pancreas islet. Original magnification: 40X. BOTTOM ROW: Immunofluorescent staining of Islet-1 in spontaneously differentiated human embryonic stem (ES) cells (left panel) and mouse pancreatic tumor (insulinoma) cells (right panel). Spontaneously differentiated (Emre et al., 2010) H9 human ES cells (WiCell, Madison, WI) and Beta-T-C6 cells (ATCC, CRL-11506™) were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), permeabilized with BD Phosflow™ Perm Buffer III (Cat. No.558050), and stained with Purified Mouse anti-Islet-1 monoclonal antibody (pseudo-colored green) at 1.25 μg/mL. The second-step reagent was Alexa Fluor® 488 goat anti-mouse Ig (Life Technologies). Nuclear staining (pseudo-colored blue) was either with DAPI (left panel) or Hoechst 33342 (Cat. No. 561908, right panel). The images were captured on a BD Pathway™ 435 Cell Analyzer and merged using BD AttoVision™ Software.
