Monocytes, as part of the innate immune system, act as the first line of defense against foreign invaders. One of their primary functions is phagocytosis, a crucial process in which they engulf

Lab Methods · CentrifugationRPM to G-Force (RCF) Conversion: Formula, Calculator Method and Common ErrorsA protocol that says “spin at 3,000 rpm” is incomplete, because the force a sample experiences

Imagine an elite squad of soldiers sent to neutralize a hidden fortress, only to find themselves wandering aimlessly in a thick, disorienting fog just outside the gates. This is the current reality f

Quick Facts About PraluzatamabWhat is Praluzatamab?Praluzatamab is an experimental monoclonal antibody that targets CD47, a “don’t eat me” signal used by cancer cells to evade immune des

For decades, the primary strategy in cancer treatment has been to trigger apoptosis, a form of programmed cell death, in malignant cells. However, many cancers develop resistance to apoptosis-inducin

The antigen tells a CD4 T cell to respond; the cytokine tells it what kind of response to make. A naive CD4⁺ T cell leaving the thymus is uncommitted. Within about seventy-two hours of engaging TCR/C

RIPA (Radio Immuno Precipitation Assay) buffer is mostly used when carrying out a western blot or immunoprecipatation assay. A RIPA buffer is used in order to lyse cells and extract protein fro

When PhDs and Post-Docs start in new lab they have the best intentions to keep their lab books up to date with notes, new research methods, data, and protocol information. These best efforts us

Mononuclear phagocytes, essential in immunity and homeostasis, perform diverse roles from phagocytosis to tissue repair, influencing health and disease. Key Takeaways: Mononuclear p
