Product Description

Hygromycin B
CAS:31282-04-9
Molecular formula: c20h37n3o13
Molecular weight: 527.52
Purity: > 90%

Resistance gene:
Resistance to hygromycin B originates from the gene encoding hygromycin B phosphotransferase (HPH). So far, two sources have been found:
HPH resistance gene produced by Streptomyces hygroscopicus;
HPH resistance gene carried by endoplasmic granules of Escherichia coli, Klebsiella pneumoniae (commonly used);

Biological applications:
1) Screening and maintaining the culture of prokaryotic cells or eukaryotic cells (plant cells and mammalian cells) stably transfected with HPH + vector;
2) Due to the difference of action mode, it is often compared with G418 (geneticintm) and zeocin ™ Combined with blasticidin s, cell lines stably transfected with two different vectors were screened;
