- PBS washed cells or tissues
- Body fluid or supernatant of cultured cell
- Tissue or cell homogenate in aqueous buffer solution
- Proteins in SDS sample buffer solution prepared for 1D SDS-PAGE


* For oversease shipping of samples, protein extract in SDS sample buffer solution is prefered. This solution could be shipped at room temperature without detectable deterioration in physical and chemical property of polypeptides.





- sample loading: Analytical gels : 50-100 µg protein
Semi preparative gels : 200 ug protein

e.g. 1 x10⁶ cultured cells, 1 mg tissue
over 300mg for plant tissue

Preparative gels: up to 3 mg protein

e.g. 3~4 x 10⁶ cultured cells, 10 mg tissue
