Product Name:

p44/42 MAPK (Erk1/2) (3A7) Mouse mAb

Catalog Number:

#9107

Antibody that works well, even on low amounts of protein (1µg), without nonspecific binding.

Experimental Design and Results Summary

Applications

Western Blot

Sample

HCT-116 lysate in several concentrations

Primary Incubation

1:2000 in 5% BSA -TBS-T, O/N at 4°C

Blocking Agent

5% BSA

Secondary Incubation

1:2500 Anti-mouse in 5% BSA -TBS-T, 1h at RT

Tertiary Incubation

N/A

Detection

ECL westernsure with 30sec exposure time

Results Summary

The MAPK (ERK1/ERK2) works very well, even in high dilutions (1:2000) up to 1µg of protein as input. The signal is strong and there is no aspecific binding.

Additional Notes

p44/42 MAPK (Erk1/2) (3A7) Mouse mAb detects endogenous levels of total p44/42 MAP kinase (Erk1/2). It does not cross-react with either JNK/SAPK or p38 MAP kinase.
