31282-04-9 Usage
Description
Hygromycin B is an aminoglycoside antibiotic that has been found in S. hygroscopicus. It is active against E. coli (MIC = 150 μg/ml) and cytotoxic to both prokaryotic and eukaryotic cells via inhibition of protein synthesis. Hygromycin B has commonly been used in molecular and cell biology applications to select for transformed cells expressing the E. coli hygromycin resistance genes hyg or hph.
Uses
Different sources of media describe the Uses of 31282-04-9 differently. You can refer to the following data:
1. antibacterial, anthelmintic; LD50 ip (rat) 63mg/Kg
2. Hygromycin B, a selective antibiotic that is effective on most bacteria, fungi and higher eukaryotes, inhibits protein synthesis by interfering with translocation and causing mistranslation at the 70S ribosome
3. Hygromycin B is an aminoglycoside and a selective antibiotic agent for the hph gene. Hygromycin B inhibits protein synthesis by interfering with translocation and causing mistranslation at the 70S rib
osome
4. Hygromycin B is a trisaccharide aminoglycoside with a terminal cyclitol produced by Streptomyces hygroscopicus, reported by researchers at Eli Lily in the early 1950s. Hygromycin B belongs to the destomycin family of aminoglycosides which contain a unique cyclic structure linking the terminal saccharide. Hygromycin B exhibits broad spectrum antibiotic and anthelmintic activity, and is used as a feed additive for swine and poultry. Hygromycin B inhibits polypeptide synthesis by binding peptidyl-tRNA and preventing translocation by Elongation Factor 2.

Check Digit Verification of cas no
The CAS Registry Mumber 31282-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,8 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 31282-04:
(7*3)+(6*1)+(5*2)+(4*8)+(3*2)+(2*0)+(1*4)=79
79 % 10 = 9
So 31282-04-9 is a valid CAS Registry Number.
