Western blot - FOLR2 antibody (ab103998)All lanes : Anti-FOLR2 antibody (ab103998) at 1 µg/ml
Lane 1 : Human spleen tissue lysate - total protein (ab29699)
Lane 2 : Bone marrow (Human) Tissue Lysate
Lane 3 : Human thymus tissue lysate - total protein (ab30146)
Lysates/proteins at 10 µg per lane.
Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 32 kDa
Observed band size: 35 kDa (why is the actual band size different from the predicted?)
Exposure time: 8 minutes
FOLR2 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted. -
Immunocytochemistry/ Immunofluorescence - FOLR2 antibody (ab103998)ICC/IF image of ab103998 stained HeLa cells. The cells were 4% formaldehyde 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 ab103998 at 5µg/ml overnight at +4°C. 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) at a concentration of 1.43µM. This antibody also gave a positive result in Hek293, HepG2, and MCF-7 formaldehyde fixed cells at 5ug/ml and also in HeLa, Hek293, HepG2, and MCF-7 Methanol fixed cells at 5ug/ml.
