TL;DR: The in vitro complement inhibitory activity of the fusion proteins was shown to be similar to that of s CR1, indicating that neither the albumin-binding domains nor the presence of bovine serum albumin interfere with sCR1 function.
Abstract: A new approach has been used to extend the T(1/2) of human soluble complement receptor type 1 (sCR1) in rats. The albumin-binding domains B2A3 (BA) and B1A2B2A3 (BABA) from Streptococcal protein G were fused to the carboxyl terminus of sCR1, and the recombinant genes were expressed and amplified in Chinese hamster ovary cells. Western blot analysis and surface plasmon resonance measurements demonstrated the binding of rat serum albumin to both sCR1-BA and sCR1-BABA but not to sCR1. The in vitro complement inhibitory activity of the fusion proteins was shown to be similar to that of sCR1, indicating that neither the albumin-binding domains nor the presence of bovine serum albumin interfere with sCR1 function. Pharmacokinetic analysis showed that the T(1/2) of the distribution phase (T(1/2alpha)) was 3.3, 20.0 and 6.0 min for sCR1, sCR1-BA and sCR1-BABA, respectively. The T(1/2) of the elimination phase (T(1/2beta)) was 103, 297 and 170 min for sCR1, sCR1-BA and sCR1-BABA, respectively. The plasma elimination of sCR1-BA and sCR1-BABA was significantly (P < .05) prolonged as compared to sCR1. The proteins showed similar tissue distribution; at 4-hr postdosing, the highest levels of 125I-radioactivity per gram of tissue were localized in the urine, blood, liver, stomach, and small intestine.

TL;DR: The authors' human cell-based data provide the first direct evidence that albumin-bound bilirubins, especially delta bilirUBin, are potent circulating cytoprotectors.
Abstract: Synthetic delta-bilirubin (i.e., bilirubin that is covalently bonded to albumin) and, to a lesser extent, bilirubin that is physically adsorbed to albumin substantially prolonged the survival of human ventricular myocytes against in situ generated oxyradicals. This cytoprotection, manifested at micromolar concentrations of either form of bilirubin, surpasses those given by unconjugated bilirubin alone, by equimolar levels of albumin (which has some cytoprotective activity), by known antioxidants ascorbate, mannitol, or Trolox, and by oxyradical scavenging enzymes superoxide dismutase (24,200 IU/L) plus catalase (92,000 IU/L) on the same cells. Our human cell-based data provide the first direct evidence that albumin-bound bilirubins, especially delta bilirubin, are potent circulating cytoprotectors. The latter may be important in defending, among others, the myocardium, which is much less equipped in antioxidant defences than for example the liver or intestines.

TL;DR: Cellular binding experiments revealed that AGE‐bovine serum albumin (AGE‐BSA) showed the specific binding to CHO cells overexpressing bovine LOX‐1 (BLOX‐1), which was effectively suppressed by an anti‐BLox‐1 antibody.

TL;DR: The sensitivity, accuracy, and reproducibility of the FIA for measuring UAE in normal subjects are reported, which are more sensitive than radial immunodiffusion methods and has been shown to accurately measure human albumin and immunoglobulin levels in saliva.
