Brdu labeling kit

Manufactured by Roche
Sourced in United States

The BrdU labeling kit is a laboratory product designed to detect cell proliferation. It allows for the incorporation of bromodeoxyuridine (BrdU) into newly synthesized DNA, which can then be detected using specific antibodies. The kit provides the necessary reagents and protocols to perform this analysis.

Cell viability was determined by Alamar blue assay. Briefly, cells were plated into a 96-well plate at the concentration of 3 × 104/mL. At different time point after Adv-MMP-10 infection, AlamarBlue reagent was introduced to each well at a volume of 10% of total well volume, and allowed to incubate for 2 h. Absorbance readings at wavelengths of 570 nm and 600 nm were compared to the absorbance of negative control wells containing media and AlamarBlue only.
Cell proliferation was determined using a BrdU labeling kit (Roche, Indianapolis, IN, USA). The BrdU incorporation was detected by FITC-BrdU antibody and analyzed under a fluorescent microscope. The experiments were performed in triplicate.

We detected SA-β-Gal as described (Dimri et al., 1995 (link)), using a commercial kit (BioVision). Briefly, 30,000 cells per well were seeded on a 12-well plate. Cells were fixed using 500 μL Fixing Buffer for 10 min, followed by three washes in PBS, and overnight incubation at 37°C in Staining Solution. Cells were visualized and counted using an inverted microscope.
DNA synthesis was determined using a modified BrdU labeling kit (Roche #11296736001). Cells were cultured in BrdU (20 μM in DMSO) for 24 hours, fixed in 4% neutral-buffered formalin for 10 min, and washed 3 times in ice cold PBS. Permeabilization was perform for 30 min by incubation in 0.5% Triton X-100 in PBS. Nuclear DNA was digested by a combination of DNase I and exonuclease III for 1 hour, and BrdU-containing fragments were visualized by immunofluorescence.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
