Anti-PEG Antibody News
April 2012 Review of methods to measure PEGylated compounds in biological samples.
June 2010 New anti-PEG antibodies allow sensitive detection of PEGylated compounds
AGP4 and 3.3-biotin allow sensitive detection of PEGylated proteins, nanoparticles and lipodsomes in complex biological samples.
May 2010 Universal anti-PEG receptors for imaging of PEGylated compounds
Expression of anti-PEG antibodies on cells can increase liposome and imaging uptake in cancer cells.
April 2010 Anti-PEG receptors enhances uptake of PEGylated compounds
Expression of anti-PEG antibodies on cells can increase liposome and imaging uptake in cancer cells.
March 2010 Novel PEG assay
We have developed a novel cell based assay to measure PEG in solution. You can read the publication here
2-04-09 Antibody comparison
We compared several of our antibodies with antibodies from other sources for sandwich ELISA. The combination of AGP4 for capture and 3.3-biotin for detection worked well for all tested PEGylated compounds and out-performed antibodies from other vendors.
12-25-08 New price schedule on selected antibodies
The price of our established antibodies has been reduced due to the availability of our new AGP4 and 3.3 antibodies.
12-15-08 New anti-PEG antibodies are now available
We have several new anti-PEG antibodies available.
AGP4 is a new IgM that displays similar or slightly higher binding activity to PEG than AGP3. A biotinylated version AGP4-biotin is also available for detection. AGP4 works especially well as a capture antibody for sandwich ELISAs. Lower concentrations of AGP4 (0.25 mg/well) capture PEGylated compounds more effectively than 1 mg/well AGP3!
3.3-biotin is a new high affinity IgG1 monoclonal anti-PEG antibody. This antibody displays higher affinity for PEG than E11 and is an effective detection antibody.
