Purified Mouse anti-Islet-1
Purified Mouse anti-Islet-1

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.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  5. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

Q11-465

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.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
