Nkx-2.5 Antibody (A-3) is a mouse monoclonal IgG1 kappa light chain antibody that detects Nkx-2.5 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). anti-Nkx-2.5 antibody (A-3) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Nkx-2.5, also known as cardiac specific homeobox protein (Csx), is a crucial transcription factor belonging to the Nkx-2 gene family, which plays a vital role in regulating the expression of genes specific to cardiac and other tissues. Nkx-2.5 is primarily located in the nucleus, where direct DNA binding influences the transcription of genes essential for heart development and function. This nuclear localization enables direct interaction with target genes involved in cardiomyocyte differentiation and cardiac morphogenesis. During embryonic development, Nkx-2.5 is expressed in various tissues, including the foregut, thyroid, spleen, and stomach, but expression becomes predominantly restricted to the heart in adults. Disruptions in Nkx-2.5 function due to mutations can lead to severe developmental issues, such as atrial-septal defects and congenital heart disease, underscoring its importance in cardiovascular health.

When should the TransCruz reagent sc-376565 X be used instead of the standard form sc-376565?

Asked by: jenniferc
Thank you for your question. We recommend using the TransCruz reagent form when performing ChIP or GelShift assays. This form can also be used in other applications such as Western Blot or IHC, but the dilution should be adjusted by a factor of 10 to account for the higher original concentration.
