Dimethylformamide (DMF) and trifluoroacetic acid (TFA) were supplied by M/s Molychem (P) Ltd., India. Sodium acetate and sodium hydroxide were procured from M/s Qualikema Laboratory Reagents, India. Sodium chloride and glacial acetic acid were purchased from Loba-Chemie (P) Ltd., India. ...
Samples were labeled with CyDye DIGE Fluor minimal dye (GE Healthcare) reconstituted in fresh 99.8% anhydrous dimethylformamide at 50 μg protein to 400 pmol Fluor dye. The labeling reaction was performed on ice in the dark for 30 min. Samples from ovarian follicles of prepubertal and mature ...
polymers has traditionally been conducted using a differential refractive index detector (RID) because many synthetic polymer compounds don’t have the functional groups for UV absorbance and the solvent for GPC mobile phase such as tetrahydrofuran (THF) and N,N-Dimethylformamide (DMF) absorb ...
