Total 240 AA. Mw: 25.9 kDa (calculated). C-Terminal Flag-tag, 10AA (highlighted). The AA sequence is identical to Swiss-Prot- P52823.
Amino Acid Sequence
His 2 to Glu 5 were confirmed by N-terminal sequencing
12% SDS-PAGE separation of Human Stanniocalcin-1
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 20mM Tris buffer, 50 mM NaCl, pH 7.5
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, Cell culture and/or animal studies
At ambient temperature. Upon receipt, store the product at the temperature recommended below.
Store the 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.
