Seroconversion Implications in SARS-CoV-2 Diagnostic Testing Key Points: COVID-19, the pandemic

PD-1 does not switch a T cell off; it moves the threshold. Engagement of PD-1 by PD-L1 recruits a single phosphatase into the immunological synapse, and that one recruitment event is enough to collap

Block one receptor and more than 90% of the microglia in a mouse brain are dead within a week. Not impaired — gone. Stop the block and they come back, repopulating from the survivors within another w

Immunology · Cell BiologyCells of the Innate Immune System: Types, Functions and MarkersThe innate immune system responds within minutes, without prior exposure, using cells that recognise conserved m

Imagine a battlefield where the enemy doesn't just hide from soldiers—it actively sabotages their weapons. In the tumor microenvironment, cancer cells have evolved a devious strategy: they transfer th

Nanosilver is the most commercialised nanoparticle routinely used for its antibacterial purposes in food preservation, cosmetic and health products such as medical devices and wound treatmen

In the intricate dance between the immune system and cancer, tumors often deploy cunning strategies to evade destruction. A groundbreaking 2025 study in Nature has unveiled a startling new tactic: can

QUICK ANSWER If your ELISA returns sample concentrations that are orders of magnitude too high, the assay itself is usually fine — the error is almost always in data analysis. The most

Fibroblasts, essential components of connective tissues, play vital roles in maintaining tissue structure and function. Their remarkable ability to produce and organize the extracellular matrix

Quick answer On the Dog Beta-endorphin (BEP) ELISA Kit, a researcher ran the same canine serum aliquots on two plates from the same lot and saw roughly double the concentration on one

Quick answer A researcher measuring circulating lipopolysaccharide (LPS) in human serum with our LPS ELISA saw almost no color, even after 30 minutes with substrate. Samples had been test
