1_W17241A_PURE_PIEZO1_Antibody_3_011222
IHC staining of purified anti-PIEZO1 (clone W17241A) on human bladder. Tissue was fixed with Fixation Buffer (Cat. No. 420801), blocked with 5% FBS + 5% Normal Blocking Serum (Cat. No. 927503), and incubated with 10.0 µg/mL purified rat IgG2b, κ isotype control (Cat. No. 400602) (panel A) or 10.0 µg/mL of anti-PIEZO1 antibody (panel B) overnight at 4°C. This was followed by incubation with Alexa Fluor® 647 Goat anti-rat IgG (Cat. No. 405416) at 2.5 µg/mL. Nuclei were counterstained with DAPI (blue) and the slide was mounted with ProLong™ Gold Antifade Mountant. The image was captured with a 40X objective. Scale: 50 µm

    Whole cell lysates from HeLa (15 μg) untreated or treated with non-targeting siRNA (siCON) or siRNA targeting PIEZO1 (siPIEZO1) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane and probed with 1.0 μg/mL (1:500 dilution) of purified anti-PIEZO1 (clone W17241A) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-rat IgG (Cat. No. 405405) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:50000 dilution (lower). Lane M: Molecular weight marker

    Whole cell extracts (15 µg total protein) from HeLa, A-431, and PC-3 cells were heated to 37°C for 30 minutes and resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 1.0 μg/mL (1:500 dilution) purified anti-PIEZO1 (clone W17241A) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-rat IgG (Cat. No. 405405) at a 1:3000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Direct-Blot™ HRP anti-β-actin (Cat. No. 643807) was used as a loading control at a 1:10000 dilution (lower). Lane M: Molecular weight marker

Description

PIEZO1 and its paralog PIEZO2 are members of a non-selective cationic mechanosensitive channel family first discovered in a neuronal cell line through mechanical stimulation. It responds to mechanical forces such as static pressure, shear stress, and membrane stretch events by allowing the efflux of calcium ions from the ER lumen into the cytosol. The increase in cytosolic calcium results in phosphorylation of ERK1/2 and a commensurate induction of downstream mitotic genes, and can also promote prostate cancer development via activation of the Akt/mTOR signaling axis. PIEZO1 is overexpressed in many tumors and is a key regulator of tumor stiffness.

Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 1.0 - 10.0 µg/mL is suggested. For western blotting, the suggested use of this reagent is 1.0 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

When testing this clone for western blot, we observed a considerable loss of signal with lysates that were boiled in sample buffer compared to samples that were heated to 37°C. This is likely due to high temperatures causing aggregation of PIEZO1, which is a multi-pass transmembrane domain protein.

This clone was tested for immunocytochemistry on HeLa cells fixed with 4% PFA and permeabilized with either methanol or Triton X-100. Both methods resulted in high non-specific staining.
