发帖数: 627 | 14 Short peptides may have low immunogenecity. To increase the chance of
getting Ab, you can synthesize a peptide dendrimer from C TERMINUS to N
terminus (as all peptide synthesis is from C to N): as following:
EK(K(K(linker-your peptide)2)2)2.
In this way, you will have a dendrimer that have 2^n of your peptides
presented outwards. This kind of dendrimer has increased immunogenecity and
therefore higher chance to generate Ab.
Anaspec should have this service although a bit expensive.
good luck. |

It said "We utilized dynamic light scattering (DLS) to identify the
size of the dendrimer particles in 10-4 and 10-5 M solutions,.......
dendrimer 6 exhibited particles with an average size of about 2.8 nm."
Are 2.8 nm too small for DLS? What is the limit of DLS?
