Description: Cell Biolabs? HDL and LDL/VLDL Cholesterol Assay Kit measures the cholesterol levels of HDL and LDL/VLDL fractions in serum, plasma, lysate, or tissue samples. The assay will detect total cholesterol (cholesteryl esters plus free cholesterol) in the presence of cholesterol esterase or only free cholesterol in the absence of the esterase enzyme.

Description: Recombinant proteins expressed in bacteria often form inclusion bodies, especially when they are expressed at high levels. The Rapid GST Inclusion Body Solubilization and Renaturation Kit is designed to retrieve expressed GST fusion proteins in soluble form after lysis and extraction procedures. Each kit contains sufficient reagents to solubilize and renature up to 5-10 liters of bacterial culture.

Description: Ultracentrifugation of lipoproteins such as HDL, LDL and VLDL can be tedious and time consuming. The LDL/VLDL and HDL Purification Kit provides comparable purity without the need for an ultracentrifuge. Samples are separated into fractions containing HDL or LDL plus VLDL and then further purified using standard table-top centrifugation speeds.

Description: Alkaline Phosphatase (AP) is a widely used marker for both mouse and human embryonic stem cells (ES) and embryonic germ cells (EG). Our StemTAG Alkaline Phosphatase kits provide an efficient system for monitoring cell differentiation or undifferentiation using the AP marker. The StemTAG Alkaline Phosphatase Activity Assay Combo Kits provide reagents for monitoring alkaline phosphatase activity via immunocytochemistry staining as well as in a 96-well plate with either colorimetric or fluorescence detection.

Description: S-adenosylmethionine (SAM) is a substrate for methyl transfers to various biomolecules that yields S-adenosylhomocysteine (SAH). SAH is then hydrolyzed to homocysteine and adenosine, which is converted to methionine, and ultimately back to SAM. SAH can act as a methylation inhibitor, therefore the SAM/SAH ratio, or methylation potential, is important for maintaining proper methylation in the cell. Our S-Adenosylmethionine (SAM) and S-Adenosylhomocysteine (SAH) ELISA Combo Kit is designed for detection and quantitation of both SAM and SAH in plasma, serum, lysates, or biological fluid samples. This assay is a competitive ELISA where samples and an anti-SAM or anti-SAH antibody are added to a plate coated with a SAM or SAH conjugate. The sample and conjugate compete for antibody binding, which generates a reverse curve. Samples with high SAM and SAH levels will bind the majority of the antibody, which gets washed away and results in a low OD, while samples with low SAM and SAH levels will leave more antibody available to bind to the conjugate, producing a high signal.
