Applications Western Blot Sample Jurkat Lysates Detection ECL solution
"Our lab is identifying IL-2 receptor components in non-lymphoid primary cell lines. We use Jurkat (E6-1) cell lines as a positive control for our experiments. Got one single band at the correct size. Very sensitive, can use at low concentration. Great antibody. Works well with whole cell lystes from our cell lines."
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
