Speedy 28-Day Polyclonal Antibody Service

When traditional protocols can take 70+ days, the wait for high-quality custom polyclonal antibodies can be excruciating. AnaSpec, EGT Group asked, "Is there a way to develop custom antibodies faster without sacrificing quality in the finished product?" Here's the answer.

The Speedy 28-day custom polyclonal antibody protocol uses a proprietary mixture of Freund's free immuno-stimulatory compounds. Antibodies can be raised against peptide sequences consisting of standard, phosphorylated, methylated or acetylated amino acids. Bleed is guaranteed to have a titer of at least 1/125,000 for one of the immunized rabbits.

Figure 1. The Speedy 28-day polyclonal antibody protocol was used to raise an antibody against an acetylated peptide. ELISA results show that the high titer antibody was specific towards the acetylated peptide.

Figure 2. The Speedy 28-day polyclonal antibody protocol was used to raise an antibody against a phosphorylated peptide. ELISA results show that the antibody had high titer and was specific towards the phosphorylated peptide.
