Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Janine (Verified Customer) (06-13-2024) | Excellent detection (tested dilution 1:1000). I used 5%BSA instead of 5% milk but the performance was still very good.
|
FH Tsimafei (Verified Customer) (06-01-2022) | mESCs express HA-SPOT-GFP protein. 20µg of total protein extract were loaded on the gel. Membrane was probed with anti-SPOT antibodies (1:1000 dilution in 3% milk) at 4C, ON.
 |
FH Daniela (Verified Customer) (04-11-2022) | The 28A5 Spot-antibody was tested in Western blots of Expi-293F supernatants and purified proteins in a 1:5000 dilution using 5% non-fat milk (Biozym)/TBST (or 1x Rotiblock solution (Roth). Incubation was either 2 h at RT or ON at 4°C. Secondary HRP-antibody was incubated for 1 h at RT. The antibody is working fine, monomers, dimers, oligomers of the construct can be distinguished.
