Lamin A Antibody (4A58) is a mouse monoclonal IgG3 antibody designed to detect Lamin A, also known as LMNA or A-type lamin, across multiple species including mouse, rat, human, bovine, and canine. Lamin A is a crucial component of the nuclear lamina, a dense fibrillar network that provides structural support to the nuclear envelope, ensuring nuclear integrity and maintaining the proper organization of chromatin. This protein features a characteristic tripartite structure with a central alpha-helical rod domain flanked by globular head and tail domains, which facilitate the formation of a stable intermediate filament network essential for cellular stability and gene regulation. The structural integrity provided by Lamin A is vital for various cellular processes, including DNA replication, transcription, and the regulation of the cell cycle, making Lamin A indispensable for maintaining cellular longevity and function. Lamin A is processed from its precursor, prelamin A, through a series of post-translational modifications, highlighting Lamin A′s dynamic role in nuclear architecture. Anti-Lamin A antibody (4A58) is raised against a partially purified recombinant human Lamin A protein, and does not cross-react with Lamin C, a closely related splice variant. Lamin A (4A58) antibody is versatile for use in western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA) applications, providing reliable and consistent results for researchers studying nuclear structure, gene expression regulation, and laminopathies. Anti-Lamin A antibody (4A58) facilitates advancements in understanding the molecular mechanisms underlying various diseases linked to LMNA mutations.

I want to use sc-71481 for immunofluorescence , will it recognize prelaminA and progerin also?

Asked by: xue chen
Thank you for your question. This mouse monoclonal antibody, Lamin A (4A58): sc-71481, is raised against partially purified recombinant Lamin A protein of human origin. The antibody has an epitope mapping between amino acids 598-611 of Lamin A. According to Uniprot (http://www.uniprot.org/uniprot/P02545), this epitope is conserved in Prelamin A and Progerin (also designated isoform 6). Therefore, this antibody could potentially recognize these other forms of Lamin A if they are expressed in your samples. This has not been experimentally evaluated in our own testing of the antibody.

I am using Lamin A (4A58): sc-71481 for immunofluorescence, what dilution of this antibody should I use?

Asked by: Professor Griffin
Thank you for your question. We recommend a starting dilution of 1:50. However, optimal antibody concentration should be determined by titration. Please find our full immunofluorescence protocol here: https://www.scbt.com/scbt/resources/protocols/immunofluorescence-cell-staining

Rated 5 out of 5 by from Useful for IFI compared C-3 (sc-518013), 4A58 (sc-71481) and 4E7A6 (sc-293162) for IF of both MEF wt and MEF Lmna-/-. C-3 and 4A58 are specific and useful for IF with MEFs in our condition (4%PFA 15min fixation followed 1:500 dilution / 4C overnight reaction).
