Purity as determined by densitometric image analysis: 90 %
14% SDS-PAGE separation of Human GLP-1R
1. M.W. marker – 97, 66, 45, 31, 21, 14 kDa
2. reduced and boiled sample, 5μg/lane
3. non-reduced and non-boiled sample, 5μg/lane
< 1.0 EU/ug
Filtered (0.4 μm) and lyophilized in 0.5 mg/mL in 0.05 M Acetate buffer pH=4.0
Add 0.1M Acetate buffer pH=4.0 to prepare a working stock solution of approximately 0.5 mg/mL and let the lyophilized pellet dissolve completely at 37°C. For conversion into higher pH value, we recommend intensive dilution by relevant buffer to a concentration of 10μg/mL. In higher concentrations the solubility of this antigen is limited. Filter sterilize your culture media/working solutions containing this non-sterile product before using in cell culture.
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.
