Labome curates formal publications to compile a list of antibodies with unambiguous specificity within Validated Antibody Database (VAD).

Antibody information

Rabbit monoclonal IgG

Company: Cell Signaling

Antibody: YAP

Catalog number: 14074

Summary: Rabbit monoclonal IgG against a recombinant protein specific to the carboxy terminus of human YAP protein. The epitope corresponds to a region surrounding Pro435 of human YAP isoform 1. This sequence region is 100% conserved among all known isoforms of human YAP proteins. Reacts with human, mouse, rat, hamster, and monkey. It is predicted to react based on 100% sequence homology with bovine, guinea pig, and horse. Suitable for western blot, immunoprecipitation, immunohistochemistry (paraffin), immunofluorescence/immunocytochemistry, flow cytometry, chromatin IP and chromatin IP-seq.

Validation Method

Immunohistochemistry

Sample

Retinas from WT and Yap/TaziΔEC mice. eyeballs were enucleated and fixed in 4% paraformaldehyde (PFA) for 20 min at room temperature (RT). After dissection, the retinas were additionally fixed in 1% PFA for 1 hr at RT.

Blocking agent

5% donkey (or goat) serum in PBST (0.3% Triton X-100 in PBS) for 30 min.

Primary incubation

Antibody diluted in blocking solution and incubated at 4°C overnight.

Secondary incubation

FITC-, Cy3-, or Cy5-conjugated anti-rabbit IgG (Jackson ImmunoResearch) diluted in blocking solution and incubated at RT for 2 hr.

Detection

Confocal microscope (Zeiss, LSM880) and processed with imaging softwares, ZEN (Zeiss) and Adobe Photoshop (Adobe).
