Name : Biotinylated Human Midkine Protein

Product Source :
Recombinant Biotinylated Human Midkine Protein is expressed from E.coli with His tag and Avi Tag at the N-Terminus. It contains Val21-Asp143.[Accession | P21741-1]

Molecular Weight :
The protein has a predicted MW of 16.46 kDa same as Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per μg by the LAL method.

Purity :
> 95% as determined by Tris-Bis PAGE

Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Biotinylated Human Midkine on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

Background :
Midkine is a heparin-binding growth factor, originally reported as the product of a retinoic acid-responsive gene during embryogenesis, but currently viewed as a multifaceted factor contributing to both normal tissue homeostasis and disease development. Midkine is abnormally expressed at high levels in various human malignancies and acts as a mediator for the acquisition of critical hallmarks of cancer, including cell growth, survival, metastasis, migration, and angiogenesis.

Synonyms :
MK; ARAP; MDK; MEK; MK1; MKARAP; NEGF2
