Multicolumn purifications are tedious and the manual operations during this process introduce variabilities, affecting the success of purification and reproducibility of results. This whiteboard animation explains how an automated multi-dimensional chromatography method can make this an easier process with very high success rates.

To run a core flow cytometry lab is no easy task. There is always a balance between running simple sorts and developing new assays for answering complicated questions that demand pushing the limits of existing assays and the limitations of the sorters. See how Andy Riddell, a flow core manager, pushes the limits of his existing assays and how Bio-Rad’s S3e™ cell sorter is allowing him to accomplish that.

Interference from IgG heavy (~ 50 kD) or light (~25 kD) chains is very common when trying to visualize bands of immunoprecipitated proteins. If your band of interest has a molecular weight close to these, it becomes really hard to distinguish between the IgG and the band of interest. How could this be avoided? Bio-Rad’s new TidyBlot™ Western Blot Detection Reagent accomplishes this by binding exclusively to the native nondenatured antibodies rather than any IgG in the sample. Explore the performance characteristics of this new reagent.

Tumor metastasis is a complex process. It requires the ability of the cancer cells to invade their surroundings and travel to distant sites and survive. Dr. Traci Lyons studies the mechanism of COX-2 functioning in the metastasis of breast cancer cells. Find out how Dr. Lyons used Bio-Rad’s PrimePCR™ Assays to confirm COX-2 knockdown at the mRNA level.

Multiplex immunoassay development requires a lot of validation and standardization steps. Several factors can influence the performance of these assays. Some factors that need to be considered are mentioned here.

Not all antibodies are created equal. Some have to work hard to qualify to become Bio-Rad’s PrecisionAb™ Antibody. Here is a diagrammatic representation of how the qualification criteria are determined.

The separation of monomers from product-related impurities is quite challenging in process separations. It requires a thorough screening and an efficient resin to get efficiency in the purification process. Review the performance data of Bio-Rad’s mixed mode CHT™ Ceramic Hydroxapatite in achieving process separation efficiency and how it compares with various Capto media.

Removing genomic DNA contamination from cDNA preparations is a challenge. All currently available methods are time consuming, could lead to sample loss, and are not efficient. Bio-Rad’s iScript™gDNA Clear cDNA Synthesis Kit tackles these issues and makes this step effortless. This article presents the performance data of the kit and describes how simple and efficient it is to use the kit for gDNA removal.

Choosing the right primary antibody is an arduous task. A lot of standardization needs to happen before we can determine that the antibody is specific and sensitive enough for the purpose of our experiment. The new PrecisonAb™ Antibodies from Bio-Rad go through vigorous testing and validation before they are deemed suitable, thus eliminating the process of trial and error for researchers. The video describes how the PrecisionAb antibodies are developed.

The best chromatography media should yield high protein purity and product recovery as well as be versatile enough to purify difficult samples. Bio-Rad’s CHT™ Ceramic Hydroxyapatite achieves this by virtue of being able to interact with the proteins through multiple modes, making the process extremely efficient. The whiteboard animation describes the mode of action of CHT.
