Antibody information

Mouse monoclonal IgG2b

Company: DSHB

Antibody: Isl1

Catalog number: 39.4D5

Summary: Mouse monoclonal IgG2b against a recombinant fusion protein containing aa. 178-349 of rat Isl1 protein (C-terminus). It also detects Islet-2. Reacts with altricial fish larva, chicken, ferret, fish, frog, human, mouse, rat, and zebrafish. Suitable for western blot, immunofluorescence, immunohistochemistry (paraffin), chromatin immunoprecipitation, and gel supershift.

Validation Method

Western blot

Sample

Control and Isl1-/- cardiac progenitor cells (derived from mESCs). Cells were lysed with lysis buffer (50 mM Tris pH 7.5, 10 mM EGTA, 100 mM NaCl, 0.1% Triton X-100) plus protease and phosphatase inhibitors on ice.

Primary incubation

1:10 dilution.
