Lactate Dehydrogenase Assay Kit is a colorimetric kinetic determination of lactate dehydrogenase activity. Lactate Dehydrogenase (LDH) is an oxidoreductase which catalyzes the interconversion of lactate and pyruvate. This video shows the procedures of the kit.
Lentivirus is a genus of slow viruses of the Retroviridae family that have long incubation periods and cause chronic, progressive, often fatal diseases affecting many organs in humans. This video shows you how to infect culture cells with lentivirus. It is an important step before the production of lentiviral vector.
This video presents the protocol for relative titer method for lentivirus. Lentivirus titers are estimated as relative infectious units (RIU), according to the curve of cell viability versus viral dose.
An agar plate is a Petri dish that contains a growth medium (typically agar plus nutrients) used to culture microorganisms. We show you how to prepare the LB agar plate.
Lentiviruses are able to deliver genes into almost any mammalian cell type and have the ability to replicate in non-dividing cells, so they are one of the most efficient methods of a gene delivery vector. This video presents the process of lentiviral production in 6cm plate.
LB broth is used for maintaining and cultivating recombinant strains of Escherichia coli. The ingredients of LB broth are tryptone, yeast extract and Sodium Chloride. We show you how to prepare the LB medium.
Firefly luciferase is widely used as a reporter to study gene expression and other cellular events. The Luciferase Assay is an extremely sensitive and rapid reagent for quantitation of firefly luciferase. Through the assay, light is produced by converting the chemical energy of luciferin oxidation and can be measured by a luminometer.
LEP (Human) Clinical Range ELISA Kit is a sandwich enzyme immunoassay for the quantitative measurement of human leptin in serum, plasma and tissue culture medium. This video shows the procedures of the kit.
Biological materials often are dried to stabilize them for storage or distribution. Lyophilization also called freeze-drying, is one method of drying biological materials that minimizes damage to its internal structure.
