Description
General description
Dependent upon the molecular weight of the tyrosine phosphorylated protein being detected.
The 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.
Immunogen
4G10 used Phosphotyramine coupled to KLH and PY20 used phosphotyrosine conjugated to carrier protein.
Application
Anti-Phosphotyrosine Antibody, 4G10 Platinum is an antibody against Phosphotyrosine for use in WB, IF, FC, IH, IP, IC, ELISA.
