Cell Culture Buffers: Types, Uses, and How to Choose
Cell culture buffers keep cells healthy outside the incubator and during routine handling. They maintain a stable pH, hold the right osmotic balance, and supply the inorganic ions cells need…
Cell Culture Serum: Types, Uses, and How to Choose
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: Key Differences and When to Use Each
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: Key Differences and When to Use Each
EBSS and HBSS are balanced salt solutions used for washing, transport, dilution, and short-term cell handling. Both help maintain osmotic balance and supply inorganic ions, but their typical bicarbonate concentrations…
Horse Serum vs FBS: Key Differences and When to Use Each
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…
The Necessity of NOT Using Whey Instead of Pure Amino Acids in Cell Culture Media
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…
Advances in MEM Formulation for Regenerative Medicine
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…
DPBS in Stem Cell and Tissue Engineering Applications
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 – Which One to Use?
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…
When to Switch from MEM to GMEM?
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…
