LPS-EK

货号： tlrl-eklps      产品名称： LPS-EK   品牌： Invivogen 规格： 5 mg 二周到货 生化试验

LPS-EK
LPS from E. coli K12
InvivoGen provides LPS-EK with two grades of purity:
•  LPS-EK is a standard lipopolysaccharide (LPS) preparation. It was extracted by a phenol-water mixture. LPS-EK contains other bacterial components, such as lipopeptides, and therefore stimulates both TLR4 and TLR2.
• Ultra-pure LPS-EK was extracted by successive enzymatic hydrolysis steps and purified by the phenol-TEA-DOC extraction protocol.  Ultrapure LPS-EK only activates the TLR4 pathway.
Working concentration: 1 ng – 10 µg/ml
Endotoxin level: 1 x 106 EU/mg
LPS-EK
Specificity: TLR4 and TLR2 agonist
LPS-EK Ultrapure
Specificity: TLR4 agonist

PGN-EK

货号： tlrl-pgnek      产品名称： PGN-EK   品牌： Invivogen 规格： 1 mg 二周到货 生化试验

PGN-EK
Peptidoglycan from E. coli K12
Peptidoglycan (PGN) is a major surface component of Gram-positive bacteria. It is embedded in a relatively thick cell wall and is usually covalently attached to other polymers, such as lipoproteins and LTAs. PGN is known to be a potent activator of NF-κB and TNF-α through TLR2. However, other pattern recognition proteins have been reported to mediate the immunostimulatory activity of PGN. This discrepancy is attributed to the method of purification. PGN-EK is purified from E.coli K12.
Specificity: TLR2 agonist (and weak TLR4 agonist)
Working concentration: 1 – 10 μg/ml
Endotoxin level:  102- 103 EU/mg
Appearance:  White lyophilized powder
