- Review by Maria Teresa Dell'Anno
"This Antibody Works Perfectly!"

Applications Immunohistochemistry Sample Spinal cord Detection Confocal microscope
"I used it for IHC on frozen sections at a dilution of 1:500. It did not need several trials to optimize the protocol. No bad things overall. I will purchase it again."
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.,
