Anti-Histone H3 antibody

Catalog Number:

ab1791

The main thrust of our lab is chromatin biology and the study nuclear architecture. Therefore, we routinely study histone proteins and their post-translational modifications. We use this antibody as a measure of total histones and for assessing the quality of nuclear and cytosolic fraction preparation.

Experimental Design and Results Summary

Applications

Western Blot

Sample

Nuclear and cytosolic fraction prepared from HeLa cells

Primary Incubation

1:5000 dilution in TBST buffer with 0.1% Tween-20

Blocking Agent

5% non-fat dry milk in TBST buffer with 0.1% Tween-20

Secondary Incubation

1:20000 Secondary goat anti-rabbit HRP antibody

Tertiary Incubation

N/A

Detection

Bio-Rad Clarity ECL substrate

Results Summary

The antibody is very specific with high affinity. I could detect strong and saturated band even with only 5 micrograms of sample and highly diluted primary and secondary antibodies. It gives a single band at around 17 kDa.
