General description

Albumin from rat serum comprises N-terminal signal and pro-peptide sequence. It has more tyrosine residues than human albumin and has a single tryptophan residue.

Application

Albumin from rat serum has been used:
  • as a standard in rocket electrophoresis for quantification of cerebrospinal fluid and serum proteins
  • in the preparation of Alexa Fluor 488 labeled fluorescent probe for confocal laser scanning microscopy (CLSM) studies
  • as a component of perfusate solution for suspending rat erythrocytes

Biochem/physiol Actions

Rat serum albumin (RSA) is useful for exogenous ligand transport studies. The tryptophan residue is useful in fluorescence spectroscopy measurements.

Preparation Note

Prepared from albumin (A6272).
