The development of the anti-phosphotyrosine, clone 4G10 in 1989 was a monumental discovery for researchers. 4G10 was the first and 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. Now Millipore has made the best even better with 4G10 Platinum. 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 is capable.

Varies

The immunogen for 4G10 was phospho-tyramine coupled to KLH, while the immunogen for PY20 was phosphotyrosine conjugated to a carrier protein.

4G10 Platinum, Anti-Phosphotyrosine, Biotin Conjugate detects levels of Phosphotyrosine proteins & has been published & validated for use in IP.

Western Blot Analysis:
A dilution of 1:1000-2000 of this antibody detected tyrosine-phosphorylated proteins in a modified RIPA lysate from human HEK293 cells treated with 100 nM insulin.
