HY-A0089

Colistin sulfate 25+ Cited Publications Polymyxin E sulfate	Bacterial Autophagy Antibiotic	Infection
Colistin sulfate is a polypeptide antibiotic which inhibits gram-negative bacteria by binding to lipopolysaccharides and phospholipids in the outer cell membrane of gram-negative bacteria.

HY-113678

Colistin Polymyxin E	Antibiotic Bacterial	Infection
Colistin is an orally active polypeptide antibiotic. Colistin has excellent activity against various Gram-negative rod-shaped bacteria, including multidrug-resistant Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae. Colistin is associated with nephrotoxicity. Colistin can be used for the research of infections caused by Gram-negative bacilli .

	MCR-1 Protein, E.coli (Cell-Free, His-SUMO) mcr1; mcr-1; APZ14_31440; Probable phosphatidylethanolamine transferase Mcr-1; EC 2.7.-.-; Polymyxin resistance protein MCR-1	E.coli	E. coli Cell-free
	The MCR-1 protein may catalyze the addition of a phosphoethanolamine moiety to lipid A, which is associated with polymyxin resistance. This modification observed in E. coli expressing MCR-1 increased the minimum inhibitory concentration (MIC) of colistin and polymyxin B. MCR-1 Protein, E.coli (Cell-Free, His-SUMO) is the recombinant E. coli-derived MCR-1 protein, expressed by E. coli Cell-free , with labeled tag.

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
