AdipoGen N-Z-L-Homoserine lactone
Chemical. CAS 35677-89-5. Formula C12H13NO4. MW 235.24. N-Z-L-Homoserine lactone is a synthetic building block or intermediate used in the synthesis of biological active agents and analogs of bacterial quorum-sensing signaling molecules. N-Z-L-Homoserine lactone is shown to irreversibly inactivate the 3C cysteine proteinase of hepatitis A virus HAV and might be a scaffold for potent cyteine protein inhibtiors. Shown to reduce the lag phase duration LPD and increase the exponential growth rate EGR of three strains of Pseudomonas fluorescens isolated from refrigerated raw milk.
Medchemexpress LLC 4-methylumbelliferyl-α-L-iduronide 2-sulfate sodium | 2181774-46-7 | >=98.0% | 476.32 | C16H14Na2O12S | 1 MG
4-Methylumbelliferyl-α-L-iduronide 2-sulfate sodium is a fluorogenic enzymatic substrate used to measure iduronate-2-sulfatase (I2S) activity. Enzymatic hydrolysis releases the fluorescent reporter 4-methylumbelliferone (4-MU), enabling quantitative fluorescence-based assays used in lysosomal storage disease research, including screening and diagnostic applications for disorders such as Hurler syndrome. Supplied as a sodium salt powder.

Sigma Aldrich Fine Chemicals Biosciences HiTrapR Heparin High Perfo
HiTrap(R) Heparin HP columns are prepacked with Heparin Sepharose(R) High Performance for high-reSOLUTIONon purification of proteins with affnity for heparin such as DNA-binding proteins coagulation factors lipoproteins and protein synthesis factors.Immobilized heparin has two main modes of interaction with proteins. It can operate as an affinity ligand with affinity for a wide range of biomolecules including coagulation factors and other plasma proteins lipoproteins protein synthesis factors enzymes that act on nucleic acids and steroid receptors. Heparin also functions as a high capacity cation exchanger due to its anionic sulfate groups. Gradient elution with salt is most commonly used in both cases.Heparin is coupled to the Sepharose(R) High Performance base matrix via the N-hydroxysuccinamide coupling method to give high capacity performance and low leakage levels.
Sigma Aldrich Fine Chemicals Biosciences Sialic Acid Quantitation K
The Sialic Acid Quantitation Kit provides a rapid and accurate determination of total N-acetylneuraminic acid (NANA sialic acid). NANA is released from glycoconjugates using neuraminidase. The kit uses alpha(2-3 6 8 9) neuraminidase to cleave all NANA linkages including alpha(2-8) and alpha(2-9) linkages as well as branched NANA for the most accurate determination of total sialic acid content.
