Background

KLF4 is a transcription factor that works with Sp1 to activate the Laminin gamma1 chain gene. It binds the CACCC core sequence. KLF4 may be involved in the differentiation of epithelial cells and may also function in the development of the skeleton and kidney. KLF4 also has roles as both an oncogene and a tumor suppressor.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Peptides and proteins are guaranteed for 3 months from date of receipt.

Western blot shows lysates of D3 mouse embryonic stem cell line, NTera-2 human testicular embryonic carcinoma cell line, F9 mouse teratocarcinoma stem cells, and rat cortical stem cells. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat SOX2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2018) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF017). A specific band was detected for SOX2 at approximately 36 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

D3 mouse embryonic stem cell line was fixed using formaldehyde, resuspended in lysis buffer, and sonicated to shear chromatin. KLF4/DNA complexes were immunoprecipitated using 5 μg Goat Anti-Mouse KLF4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3158) or control antibody (Catalog # AB-108-C) for 15 minutes in an ultrasonic bath, followed by Biotinylated Anti-Goat IgG Secondary Antibody (Catalog # BAF109). Immunocomplexes were captured using 50 μL of MagCellect Streptavidin Ferrofluid (Catalog # MAG999) and DNA was purified using chelating resin solution. The B2R promoter was detected by standard PCR.

Molarity Calculator

Calculate the mass, volume, or concentration required for a solution.

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
