The Human Midkine is created as a recombinant protein with N terminal fusion of HisTag. The Human Midkine His-Tagged Fusion Protein, produced in E. coli, is 14.6 kDa protein containing 121 amino acid residues of the human Midkine and 10 additional amino acid residues – HisTag. UniProtKB acc.no. P21741.
Amino Acid Sequence
12% SDS-PAGE separation of Human Midkine
1. M.W. marker – 14, 21, 31, 45, 66, 97 kDa
2. reduced and heated sample, 5μg/lane
3. non-reduced and non-heated sample, 5μg/lane
Filtered (0,4 μm) and lyophilized in 0.5 mg/mL in 0.05 M phosphate buffer, 0.1 M NaCl, pH 7.2
Add PBS pH 7.2 to prepare a working stock solution of approximately 0.5 mg/mL and let the lyophilized pellet dissolve completely. Filter sterilize your culture media/working solutions containing this non-sterile product before using in cell culture
Western blotting, ELISA
At ambient temperature. Upon receipt, store the product at the temperature recommended below.
Store lyophilized protein at –80°C. Lyophilized protein remains stable until the expiry date when stored at –80°C. Aliquot reconstituted protein to avoid repeated freezing/thawing cycles and store at –80°C for long term storage. Reconstituted protein can be stored at 4°C for a week.
Quality Control Test
BCA to determine quantity of the protein.
SDS PAGE to determine purity of the protein.
