application example
An hydroxymethylated DNA IP (hMeDIP) was performed using the rabbit polyclonal antibody directed against 5-hydroxymethylcytosine. The IgG isotype antibodies from rabbit were used as negative control. The DNA was prepared with the GenDNA module of the hMeDIP kit and sonicated with our Bioruptor® to have DNA fragments of 300-500 bp. 1 μg of human Hela cells DNA were spiked with non-methylated, methylated, and hydroxymethylated fragments. The IP’d material has been analysed by qPCR using the primer pair specific for the 3 different control sequences. The obtained results show that the rabbit polyclonal for 5-hmC is highly specific for this base modification (no IP with non-methylated or methylated C bases containing fragments).

ELISA: to determine the titer, an ELISA was performed using a serial dilution of the rabbit polyclonal antibody directed against 5-hmC in antigen coated wells. The antigen used was BSA coupled to the 5-hmC base. By plotting the absorbance against the antibody dilution, the titer of the antibody was estimated to be 1: 3 500.

Background
Background
5-hmC | 5-hydroxymethylcytosine is a recently discovered DNA modification which results from the enzymatic conversion of 5-methylcytosine into 5-hydroxymethylcytosine by the TET family of oxygenases. It may have an important roles distinct from that of 5-methylcytosine (5-mC). 5-hmC bases have been identified in Purkinje neurons, in granule cells and embryonic stem cells where they are present at high levels (up to 0,6% of total nucleotides in Purkinje cells.
