What is a Recombinant Antibody and Why is it Important?


Posted by Emma E on Jul 15, 2020 3:00:00 AM

Recombinant antibodies offer several key advantages compared to traditional antibodies. These include superior lot-to-lot consistency, continuous supply, and amenability to antibody engineering. As such, recombinant antibodies are seeing increased use for scientific research, especially as a means of addressing the ongoing reproducibility crisis.

9B11 Is a Superior Clone against Top-cited Myc-tag Competitor


Posted by Tamar A. on May 20, 2020 3:15:00 AM

Biological research is about expanding knowledge, so it's not uncommon for scientists to become interested in studying proteins for which antibodies have not yet been developed. How then, can scientists pursue mechanistic studies of these novel or less-characterized proteins? Epitope tagging is a powerful tool for these protein studies and is used in myriad experimental applications. However, care must be taken not only in choice of epitope tag, but in selection and validation of antibodies.

The Importance of Research Antibody Specificity and Reproducibility During the SARS-CoV-2 Crisis


Posted by Srikanth S on May 6, 2020 3:38:00 PM

During this time of crisis, healthcare providers and researchers around the world are racing to develop SARS-CoV-2 testing methods. Testing strategies include PCR to diagnose active infection (by testing for the presence of viral genetic material) and the use of antibody test kits on blood (also known as serological tests), in order to track exposure and possible immunity in the population (1,2,3). With these diagnostic tools, the scientific community aims to get a better understanding of the scale and trajectory of the SARS-CoV-2 pandemic.

The Science Behind Sampler Kits


Posted by Chris S on Apr 29, 2020 3:00:00 AM

If one were asked to describe a Cell Signaling Technology (CST) antibody sampler kit, we would totally understand an answer like, “it’s an assortment of antibodies.” Honestly, on its face, that answer isn’t exactly wrong. It just makes the process seem a little random. Especially considering the reality:

Hallmarks of Validation - Complementary Strategies


Posted by Katie C on Apr 8, 2020 3:00:00 AM

Depending on the antigenic target being studied and the application being used, it may be advisable to employ complementary strategies during antibody validation. These approaches can provide vital information regarding antibody specificity or functionality and can be carefully tailored to the biological nature of the target as well as to the exacting requirements of the downstream assay.

Hallmarks of Validation - Heterologous Strategy


Posted by Katie C on Apr 1, 2020 3:00:00 AM

For antigenic targets where expression of the protein is very low or unknown, the use of recombinant proteins or exogenous expression in a surrogate cell line may be necessary for antibody validation. Although endogenous systems are preferred for their closer representation of in vivo conditions, heterologous strategy offers several advantages.

Hallmarks of Validation - Multiple Antibody Strategy


Posted by Katie C on Mar 18, 2020 3:00:00 AM

A multiple antibody strategy is a powerful approach to antibody validation. One of the most common methods to achieve this is to immunoprecipitate (IP) the target with one antibody and subsequently detect it by western blotting with another antibody against the same target. This provides confidence that both antibodies are binding the correct biomolecule.

Hallmarks of Validation - Orthogonal Strategy


Posted by Katie C on Mar 4, 2020 3:00:00 AM

An orthogonal strategy for antibody validation involves cross-referencing antibody-based results with data obtained using non-antibody-based methods. This approach is critical to verify existing antibody validation data and to identify any effects or artifacts that are directly related to the antibody in question. Providing an additional level of detail to support results generated by the other strategies outlined within this handbook, orthogonal validation often utilizes data which are available in the public domain.
