Amino Acid Sequence
12% SDS-PAGE separation of Human Leptin
1. M.W. marker – 14, 21, 31, 45, 66, 97 kDa
2. reduced and heated sample, 7μg/lane
3. non-reduced and non-heated sample, 7μg/lane
Biological Activity is evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor.
< 1.0 EU/ug
Filtered (0.4 μm) and lyophilized from 0.5 mg/ml in 5mM NaHCO3, pH= 7.4
Add deionized water 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.
LAL to determine quantity of endotoxin.
