Gold Biotechnology Inc 5-Fluoroorotic acid monohydrate (5-FOA) 5 g

5-Fluoroorotic Acid (5-FOA) is widely used in the field of yeast molecular genetics. The toxicity of 5-FOA to yeast cells with a functioning URA3 gene which encodes orotidine-5′-P decarboxylase (OMP decarboxylase), makes it especially useful for the selection and identification of mutant yeast strains. 5-FOA is most often applied with Saccharomyces cerevisiae (URA3), although it has been used in other strains including Schizosaccharomyces pombe (URA4 and URA5), Candida albicans (URA3) and the bacterium E. coli (pyrF). The use of 5-FOA in the yeast 2-hybrid system allows for the construction of activation domain hybrid libraries to identify protein-protein interactions.

Gold Biotechnology Inc Hygromycin B 1 g

Hygromycin B is an aminoglycoside antibiotic isolated from Streptomyces hygroscopicus. It is commonly used to study protein synthesis. Aside from its efficacy against bacteria, fungi, and higher eukaryotic cells, hygromycin B is also an antiviral agent inhibiting translation upon selectively entering cells made permeable due to viral infection. It works as a standard selection antibiotic in gene experiments, especially for selection of hygromycin resistance gene transformed cells.

Gold Biotechnology Inc Nourseothricin Sulfate (Streptothricin Sulfate) (NTC or clonNAT) 1 g

Nourseothricin is a broad-spectrum antibiotic derived from Streptomyces noursei. In addition to being effective on prokaryotic cells of gram-positive and gram-negative bacteria, various fungi including Candida albicans, and certain DNA and RNA viruses, it is also effective on eukaryotic cells of higher eukaryotes. It has been used as a selection agent for cells containing the gene conferring resistance to it.

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.
