DescriptionAnti-Phosphotyrosine Antibody, 4G10® Platinum
Background InformationThe development of the anti-phosphotyrosine, clone 4G10® in 1989 was a monumental discovery for researchers. 4G10® was the first and is the best single monoclonal antibody for the detection tyrosine phosphorylation. 4G10® is well known for its sensitivity and its ability to detect multiple tyrosine phosphorylations on numerous substrates. It has been validated by thousands of scientific and medical researchers in virtually every application and tyrosine target over the past 2 decades. To improve on something that hundred have tried and no one has succeeded, we pooled 4G10® with the next most highly regarded anti-phosphotyrosine, clone PY20 to make 4G10® Platinum. PY20 itself is a very poor substitute for 4G10®, but its additive effect allow for a greater level of detection on more substrates that even 4G10® alone was not capable of.
Product Information
  • Positive Antigen Control: Catalog #12-302, EGF-stimulated A431 cell lysate. Add 2.5µL of 2-mercaptoethanol/100µL of lysate and boil for 5 minutes to reduce the preparation. Load 20µg of reduced lysate per lane for mingels.
