Serum albumin, often referred to simply as blood albumin, is an albumin (a type of globular protein) found in vertebrate blood. The most relevant allergens originate from rodents; specifically mice, rats, guinea pigs, and rabbits. Once the underlying cause of your cat's hypoalbuminemia has been treated, follow-up visits will be necessary to ensure that both the initial problem and the low albumin levels are under control. Allergens of mammalian origin: characterization of allergen extracted from cat pelts. Serum albumins are mainly respiratory allergens; however, sensitization to SAs may be quite more complex and involve multiple routes of exposure. However, heat treatment in the presence of reducing agents was able to eliminate IgE binding, suggesting disulfide bridges were preserving the structure [26,27]. Serum albumin has many important jobs. Sensitization to one of the SAs coupled with the high degree of conservation between SAs may result in cross-reactive antibodies in allergic individuals. BMC Struct Biol 11:18. https://doi.org/10.1186/1472-6807-11-18, Zunszain PA, Ghuman J, McDonagh AF, Curry S (2008) Crystallographic analysis of human serum albumin complexed with 4Z,15E-bilirubin-IXalpha.

BSA is important in our understanding of SA allergenicity and the cross-reactivity of BSA with SAs from other animals has been studied extensively. The main functions of albumin are circulating necessary molecules throughout the bloodstream in support of metabolic processes and binding with water to stabilize blood pressure by preventing leakage from blood vessels. It has been suggested [14] that BSA should be considered an important pan-allergen in allergies to meat and mammalian epithelium. PubMedGoogle Scholar. Albumin is a protein synthesized by hepatocytes in the liver and excreted in very high quantities in the blood. The glomerular basement membrane is also negatively charged in the body; some studies suggest that this prevents the filtration of albumin in the urine. Albumin is a globular, water-soluble, un-glycosylated serum protein of approximate molecular weight of 65,000 Daltons. An imbalance of albumin and globulin proteins might suggest a problem with the liver itself, or it might be an indication of a problem elsewhere.
