ICC/IF image of ab63740 stained mouse embryonic stem cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab63740, 1µg/ml) overnight at +4ºC. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue).
All lanes : Anti-Lin28 antibody (ab63740) at 1 µg/ml
Lane 1 : MEL-1 (Human embryonic stem cell, male cell line) Whole Cell Lysate (ab27198)
Lane 2 : F9 (Mouse embryonic carcinoma cell line) Whole Cell Lysate (ab27193)
Lane 3 : E14Tg2a (Mouse embryonic stem cell line) Whole Cell Lysate
Lane 4 : Mouse EG (TMAS Embryonic Germ Cells) Whole Cell Lysate
Lysates/proteins at 10 µg per lane.
Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
Performed under reducing conditions.
Predicted band size : 23 kDa
Observed band size : 30 kDa (why is the actual band size different from the predicted?)
The 30 kDa band observed is comparable to molecular weights seen with other commercially available antibodies to Lin28.
