Most labs treat albumin like a household chemical. They grab whatever’s on the shelf, drop it into the receptacle, and move on.
Mouse Serum Albumin isn’t interchangeable with what’s already in your fridge. It’s the primary transport protein in murine plasma, responsible for carrying fatty acids, regulating colloidal osmotic pressure, and functioning as a major zinc transporter governing plasma zinc distribution at the molecular level.
Its amino acid sequence is distinct enough that substituting a generic alternative in murine-specific systems isn’t a shortcut. It’s a liability.
Our Mouse Serum Albumin is prepared as a lyophilized powder from verified murine sources, including Webster strain mouse serum, processed without cold alcohol fractionation to preserve native binding characteristics.
It’s built for surface plasmon resonance studies, affinity constant determinations, and applications where the wrong albumin species quietly ruins your data before you know what happened.
Thirty years of supplying research-grade biologicals. We know what’s at stake.
Mouse Serum Albumin is the dominant plasma protein in murine blood, with a distinct amino acid sequence that separates it biologically from other mammalian albumins. It regulates colloidal osmotic pressure, acts as a major zinc transporter controlling plasma zinc levels, and binds fatty acids and other specific molecules. It’s not a rodent-flavored BSA. It’s its own thing.
It’s used in surface plasmon resonance studies, affinity constant measurements, murine immunoassay validation, and as a species-matched blocking agent where nonspecific binding from bovine-derived proteins would compromise results.
Labs running BSA culture media protocols sometimes switch to mouse albumin, specifically when working in fully murine systems. The application determines the albumin level. Not the other way around.
The amino acid sequence differences between mouse albumin and BSA aren’t trivial in sensitive assay systems. Cold alcohol fractionation used in standard BSA production introduces processing artifacts that murine-specific work doesn’t need.
Mouse Serum Albumin, sourced from Webster strain mouse serum and supplied as lyophilized powder, gives you the species fidelity that Fractionated Albumin from porcine Serum or bovine alternatives simply can’t provide in murine models.
We need to source it from a supplier who actually stocks it consistently and understands why it matters. Equitech-Bio carries Mouse Serum Albumin, alongside goat serum albumin, and a full range of species-specific albumins for laboratory research. Available in multiple sizes, shipped from the USA, with reserve samples on request before you commit to volume.
