WB (Western Blot) (Western blot assay for Recombinant Mononucleosomes H3.1 (K9I) 0.5 ug Recombinant Histone H3.1 (K9I) which was used for assembly of nucleosomes was incubated with 0 or 5 nM G9A respectively in reaction buffer containing 50 mM Tris-HCl pH 8.6, 0.02% Triton X-100, 2 mM MgCl2, 1 mM TCEP and 50 uM SAM for 3 hr at room temperature. Half of the reactions were run on a 12.5% SDS-PAGE gel and detected with H3K9me2 antibody . Histone H3.1 was used as a control. The Western Blot result shows that only the K9 of histone H3.1 can be methylated by G9A.)

SDS-PAGE (Recombinant Mononucleosomes H3.1 (K9I) 12.5% SDS-PAGE gel stained with Coomassie Blue MW: 108 kDa Purity: >92%)

Lane 2: 601 DNA which was used for assembly of nucleosomes. Lane 3: Intact mononucleosomes H3.1 (K9I). Intact mononucleosomes H3.1 (K9I) migrated much higher than free 601 DNA. The agarose gel shows that almost all of 601 DNA wrapped histone octamers to form nucleosomes.)

What Are Recombinant Proteins?

Recombinant proteins are purified laboratory reagents produced through genetic engineering. A specific gene of interest is inserted into a host organism, such as mammalian, bacterial, yeast, or insect cells, which then expresses the protein in a controlled environment.

The recombinant process utilized to generate the recombinant proteins in our catalog provides precise control over sequence modifications, expression levels, and large-scale production tailored to experimental needs. These recombinants are widely used in research to investigate protein-protein interactions, enzyme activities, receptor-ligand binding, and cellular responses. Additionally, recombinant proteins serve as standards or controls in immunostaining assays and support cell growth and differentiation in culture systems, particularly in immunology, oncology, and structural biology studies.

Common Applications of Recombinant Proteins

• Studying protein-protein and protein-DNA interactions


• Functional assays to study biological pathways


• Standard curves in ELISA and other quantitative assays


• Use as antigens for antibody production


• Development and screening of therapeutic drugs


• Biomarker discovery and validation


• Cell signaling and immune response studies


• Vaccine research and development
