Anti podocin antibody

Manufactured by Merck Group
Sourced in United States

The Anti-podocin antibody is a laboratory reagent used for the detection and analysis of the podocin protein in biological samples. Podocin is a key structural component of the glomerular filtration barrier in the kidney. The antibody can be used in various immunoassay techniques, such as Western blotting and immunohistochemistry, to study the expression and localization of podocin in research and clinical settings.

To confirm the podocyte-specific knock out of Tfam, Pgc-1α and Drp1, respectively, podocytes were ex vivo isolated after Dynabead perfusion and several digestion steps. Finally, podocytes were captured by anti-podocin antibody (P0372, Sigma) coupled to Alexa Fluor 488 (Z25302, Thermo Scientific) (Pgc-1α) or isolated due to their GFP-signal (Tfamflox/flox;Tomato/eGFP;hNPHS2Cre+ and Drp1flox/flox;Tomato/eGFP;hNPHS2Cre+ mice). DNA was isolated using DNeasy kit (QIAGEN, 69504) following manufacturer`s instructions. PRC was performed using following primers: Tfam forward 5′-CTGCCTTCCTAGCCCGG-3′, Tfam reverse 1 5′-GTAACAGCAGACAACTTGTG-3′, Tfam reverse 2 5′-CTCTGAAGCACATGGTCAAT-3′. Pgc-1α alpha primer: Pgc-1α WT: frwd 5′-ACCTGTCTTTGCCTATGATTC, reverse 5′- CCAGTTTCTTCATTGGTGTG −3′; Pgc-1α KO forward: 5′-TCCAGTA
GGCAGAGATTTATGAC-3′, reverse: 5′-CCAACTGTCTATAATTCCAGTTC-3′.
Drp1: D1 (5′-CACTGAGAGCTCTATATGTAGGC-3′), D3 (5′-ACCAAAGTAAGGAAT
AGCTGTTG-3′) and D5 (5′-GAGTACCTAAAGTGGACAAGAGGTCC-3′).

Frozen slides with mouse kidney tissue were fixed in acetone, blocked, then incubated with primary antibodies, including anti-podocin antibody (1:100; Sigma-Aldrich, St. Louis, MO), anti-desmin antibody (1:100; Invitrogen, Carlsbad, CA), anti-Asm antibody (1:100; LSBio, Seattle, WA), anti-Cre antibody (1:100; Millipore, Temecula, CA), anti-ceramide antibody (1:100; ALEXIS, Farmingdale, NY), anti-NLRP3 antibody (1:50; Abcam, Cambridge, MA), anti-ASC antibody (1:50; Santa Cruz Biotechnology, Dallas, TX), anti-Ly6G antibody (1:50; Abcam, Cambridge, MA), anti-VPS16 antibody (1:50; proteintech, Rosemont, IL), and anti-Lamp-1 antibody (1:50; Abcam, Cambridge, MA), overnight at 4°C. Immunofluorescent staining was accomplished by incubating slides with Alexa-488 or Alexa-594-labeled secondary antibodies (Invitrogen, Carlsbad, CA) for 1 hour at room temperature [34 (link)]. Slides were washed, mounted, and observed by a confocal laser scanning microscope (FluoView FV1000, Olympus, Tokyo, Japan). Image Pro Plus 6.0 (Media Cybernetics, Bethesda, MD) was used to analyze colocalization which was expressed as Pearson correlation coefficient (PCC).

Immunofluorescence Analysis of Podocyte Markers

Check if the same lab product or an alternative is used in the 5 most similar protocols
Frozen kidney tissues were firstly cut into 4 μm thick sections and were incubated with anti-synaptopodin antibody (1:100, Santa Cruz, sc-21537), anti-podocin antibody (1:100, Sigma, P0372), anti-NFATc1 antibody (1:50, Santa Cruz, sc-13033) overnight at 4 °C, followed by incubation with fluorescein-conjugated secondary antibody. The results were examined with immunofluorescence microscopy (Leica DMLB, Wetzlar, Germany). For in vitro cultured podocytes, coverslips containing podocytes were firstly fixed with 4% paraformaldehyde and permeabilized in 0.3% Triton X-100 for 10 min. Podocytes were blocked with 10% FBS for 1 h and then incubated with FITC-phalloidin (1:100, Sigma, P5282), anti-synaptopodin, anti-podocin, and anti-NFATc1 antibody.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
