Enquire for price



G-25 Gel Filtration Desalting Columns are prepacked with a highly efficient gel filter which simplifies synthesized/end-labeled oligonucleotide purification, desalting, buffer exchange and protein purification. Low molecular weight material is retained in the gel matrix, facilitating the purification of DNA fragments larger than 10 bases in length. Since G-25 Gel Filtration Desalting Columns are designed to purify DNA fragments >10 bases only, they are not recommended for PCR product primer removal.
