Zyagen offers complet Western blot custom services including extraction of total proteins from tissues or cells provided by Zyagen or customers, construction of premade Western blots, immunostaining blots with any antibody, quantitative analysis of immunostaining, and sending high quality digital images. We can construct blots with up to 20 samples including one prestained protein marker.

Protein Extraction Services:

• Extraction and purification of protein from tissues provided by customers or Zyagen
• Extraction and purification of protein from primary cell or cell lines provided by customers
• Protein is extracted in any lysis buffer suggested by customers
• To prevent protein degradation, protein lysis buffer is supplemented with a cocktail of 7 protease inhibitors.
• Quantification of protein using highly specific and sensitive protein assays.
• Quality of protein is tested by denatured SDS gel electrophoresis
• Extracted protein is suitable for immediate use in reporter assays (e.g., luciferase, beta-galactosidase, chloramphenicol acetyl transferase), protein kinase assays (e.g., PKA, PKC, tyrosine kinase), immunoassays (e.g., Western blots, ELISAs, RIAs) and/or protein purification procedures, immunoprecipitation,
• SDS-PAGE, isoelectric focusing gels and SDS-capillary electrophoresis, enzymatic activity analysis, gel shifting assay, and protein-protein interaction.
• Protein is provided in protein lysis buffer or denatured SDS sample buffer at any concentration suggested by customers
• Protein is shipped on dry ice

Construction of Premade Western blotting Services:

• Harvesting fresh tissues/cultured cells provided by Zyagen or customers.
• Homogenization of tissues/cells in protein lysis buffer supplemented with a cocktail of 7 mammalian protease inhibitors.
• Quantitation of  total protein using sensitive, specific and accurate protein assay.
• Testing the purity and integrity of extracted proteins by gel electrophoresis.
• Fractionation of protein (75 microgram) through large SDS-denatured polyacrylamide gel electrophoresis.
• Transfer protein onto PVDF membranes.
• Staining blots with reversible staining to check the sharpness of protein bands and efficiency of transfer.
• Shipping blots at room temperature in sealed bags

Western Blot Analysis Services:

• Extraction of total proteins from tissues/cells provided by Zyagen or customers
• Constructions of Western blots using total proteins
• Immunostaining blots with antibodies provided by customers using ultrasensative chemiluminescent ECL detection
• Stripping antibodies from blots
• Reimmunostain blots with any house-keeping gene antibodies
• Scanning protein bands on X-ray films
