Cell culture serum is one of the most important supplements in mammalian cell culture. Added to basal media, it supplies the growth factors, hormones, attachment factors, and transport proteins that…

DMEM vs RPMI 1640 is one of the most common decisions in cell culture, because the two media were designed for very different kinds of cells. Both are nutrient-rich basal…

EBSS vs HBSS is a common question when choosing a balanced salt solution for cell culture. Both are isotonic salt solutions that maintain pH, hold osmotic balance, and supply essential…

Horse serum vs FBS is one of the most common decisions a researcher faces when choosing a serum supplement for mammalian cell culture. Both support cell growth, but they come…

Several cell culture media manufacturers keep prices low by outsourcing production overseas and shipping media as powders formulated with whey protein hydrolysate instead of pure amino acids, and with similar…

Regenerative medicine work built around mesenchymal stem cells (MSCs) has largely converged on one specific MEM variant: MEM Alpha Modification, commonly written as α-MEM. The reason comes down to a…

Dulbecco's Phosphate Buffered Saline (DPBS) shows up constantly in stem cell and tissue engineering protocols, but its usefulness in both fields comes down to one specific design choice: what it…

DEPC water vs autoclaved water is a question that only really has one right answer once you know what each process actually does to RNase, and there's a persistent lab…

Glasgow's Minimum Essential Medium (GMEM) isn't a generic upgrade to standard MEM, it's a purpose-built formulation with a specific origin story, and knowing that history is the fastest way to…

Organ-on-a-chip models are built to reproduce real tissue physiology as faithfully as possible, and hormone signaling is one of the physiological systems these platforms are most often used to study.…
