It Takes Two to Tango, Part 2: Applications of Bioconjugation

In the previous section, we discussed the methods of bioconjugation. And the marriage of a biomolecule and a small molecule has given rise to various modalities commonly used in biomedical research. Here, we focus on the applications in the fields of therapeutics, diagnostics, protein-protein interactions, and nanotechnology.

SugarGPT: Envisioning the Future of Glycoinformatics

The body’s autoimmune response has been leveraged by cancer researchers to propel immunotherapy tools into clinical use. Although the main focus has been on the ability of T-cells to fight cancer cells, the involvement of tumor-infiltrating B-cells is also becoming evident. Tumor-infiltrating B lymphocytes (TIL-Bs) are produced in much higher amounts in various cancers than in healthy tissues, which highlights their positive prognostic value (1). However, their exact role in cancer remains controversial, with the demonstration of both positive and negative impacts.

Adding efficiency and convenience to multiplexing workflows​

Multiplexing has revolutionized immunostaining workflows. It allows the simultaneous detection of multiple targets in the same tissue section and empowers scientists to gather more data while sparing precious samples. But issues with cross-reactivity between reagents can hinder the ability to perform simultaneous double or triple staining. When these issues arise, scientists can use the VectaPlexÔ Antibody Removal Kit to do multiple rounds of labeling and perform multiplexing experiments.

Immunostaining basics: What to know before starting

Observation is one of the fundamental steps in the scientific method. However, for centuries the scientific study of tissues was limited to observations of dissections with the unaided eye. It was not until the mid-19th century with the introduction of dyes, such as hematoxylin, that the subcellular structure of tissues became visible and the science of histochemistry emerged (1).

How to use VectaPlex™ Antibody Removal Kit

Multiplexing, a powerful technique that allows the visualization of multiple biomarkers within a single sample, has revolutionized the field by offering researchers valuable insights into the spatial context of complex cellular processes and interactions. By analyzing multiple targets in the same specimen, researchers can obtain a holistic view of their tissue while conserving precious sample. However, performing multiplex assays can be challenging. Cross reactivity between detection reagents can often limit reagent choices and circumventing this by directly labeling primary antibodies can lead to altered antibody function and loss of specificity. Thankfully, VectaPlex™ Antibody Removal Kit comes to the rescue, simplifying the multiplex workflow, preserving tissue integrity, and enabling multiple rounds of staining without reducing target availability.
