Medchemexpress LLC Hygromycin B | 31282-04-9 | 99.9% | 1 ML

Hygromycin B is an aminoglycoside antibiotic active against both prokaryotic and eukaryotic cells. Synthesized by *Streptomyces hygroscopicus*, it functions by strongly inhibiting both 70S and 80S ribosomes, blocking polypeptide synthesis, and preventing ribosomal translocation. It is widely used in research for its ability to halt cell growth and confers resistance in transgenic organisms expressing the bacterial *hygR* gene.

Gold Biotechnology Inc X-gluc (CHX salt) 5 g

X-Gluc is a chromogenic substrate for beta-glucuronidase (GUS) which is encoded by the gusA (uid A) gene, a widely used reporter gene. Glucuronidase cleaves X-Gluc to produce colorless glucuronic acid and an intense blue precipitate. X-Gluc is often used in GUS staining of plant cells and tissue and in infections caused by E. coli.
