Anti progerin

Manufactured by Santa Cruz Biotechnology
Sourced in United Kingdom

Anti-Progerin is a research-grade antibody product designed to detect and quantify the progerin protein. Progerin is a mutant form of the lamin A protein associated with the accelerated aging disorder Hutchinson-Gilford progeria syndrome. This antibody can be used in various analytical techniques, such as Western blotting, immunohistochemistry, and ELISA, to study the expression and localization of progerin in biological samples.

Fibroblasts were seeded into 4 chamber-well slides (SPL Lifesciences, Korea). Cells were fixed for 15 minutes (RT) in a 4% paraformaldehyde +2% sucrose solution and then permeabilized for 3 minutes at RT using permeabilization buffer (0.5% Triton X-100, 50 mM NaCl, 300 mM sucrose, 20 mM HEPES pH 7.5, 3 mM MgCl2). Cells were then incubated with primary antibodies for 40 minutes at 37 °C (anti-progerin (1/50, sc-81611) and anti-lamin A/C (1/50, sc-20681), Santa Cruz Biotechnology). After washing, cells were incubated for 20 minutes at 37 °C with secondary antibodies (A11001, A11012, 1/400 Life Technologies). Nuclei were stained with DAPI for 10 minutes at room temperature (0.1 μg/mL, Thermofisher). Slides were mounted using FluorSave™ reagent (Merck Millipore) and observed on a fluorescence microscope (ApoTome.2 Zeiss).

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.
