Overview
| Product Description | Lentivirus vector is derived from human immunodeficiency virus-1 (HIV-1), which has been widely used to transfer gene(s) of interest into dividing and non-dividing cells. The lentiviral titer, as assessed by the p24 protein content, is an essential characterization procedure for routine quality control and lot release, as well as for purification process optimization. However, HEK-293T cells will release free p24 protein into the supernatant during transfection, and this part of p24 would account for a large percentage of the total p24. The traditional p24 ELISA kit detects both lentivirus associated p24 and free p24, which will overestimate the titer of the lentivirus. GenScript’s Lentivirus Titer p24 ELISA Kit Pro(Cat. No. L00974) is a Sandwich ELISA designed for quantitatively measuring the physical titer of any HIV-1 based lentivirus in cell culture supernatant. After removing free p24 (patented technology), the amount of lentivirus-associated p24 can be measured by the p24 ELISA kit. The kit has the same linear range, detection capability, and precision with Lentivirus Titer p24 ELISA Kit (Cat. No. L00938) in the detection of p24 concentration. This kit makes lentivirus titration easy, accurate and reproducible. |

Assay Principle
| Assay Principle | The Lentivirus Titer p24 ELISA Kit Pro consists of two parts, including Lentivirus Free p24 Removal Reagent (patented technology) and Lentivirus Titer p24 ELISA Kit. Before detecting the concentration of p24 protein, free p24 in lentiviral supernatant can be specifically removed by Lentivirus Free p24 Removal Reagent. The Lentivirus Titer p24 ELISA Kit utilizes two HIV-1 p24 monoclonal antibodies which bind to different epitopes of the p24 protein. When standards or samples are added to the capture plate, the p24 protein in the sample can be captured on the plate coated with the HIV-1 p24 capture antibody. Then the HIV-1 p24 detection antibody conjugated with biotin is added to interact with the p24 protein bound on the plate. Streptavidin-Horseradish Peroxidase conjugate (Streptavidin-HRP) is added to interact with the biotin-conjugated anti-p24 antibody (Biotin Anti-p24 Antibody). After washing steps, 3,3,5,5-Tetramethylbenzidine solution (TMB Solution) is added resulting in the formation of blue color. The reaction is stopped by adding Stop Solution. Application of the Stop Solution results in the color changing from blue to yellow. The intensity of the color can be read at 450 nm by a microplate reader. The quantity of p24 protein in the sample is precisely quantified against a p24 standard curve. p24 values are then correlated to the lentivirus titer of packaging cell culture supernatants.
