Product Name:

PPM1D polyclonal antibody

Catalog Number:

PA5-72839

Clone Number:

Polyclonal

During different stages of adipogenesis of 3T3-L1, we knockdown CD24 gene to understand its regulation. One of the genes regulated was PPM1D, we validated the mRNA and had to validate the protein which never worked due to antibody we used.

Secondary Incubation

1:2000 in 5% BSA in 1 X TBST for 1 hr at room temp

Tertiary Incubation

N/A

Detection

Summary

The Good

N/A

The Bad

It doesn't detect the PPM1D protein not reliable antibody

The Bottom Line

Do not use this antibody for PPM1D detection by western blots, it is not detecting the protein of mentioned size in samples and control.
