Two journal articles cite HemogloBind™ to remove analytical interferences from Hemoglobin

MONMOUTH JUNCTION, N.J. - Sept. 9, 2021 - PRLog -- Biotech Support Group reports on two journal articles describing the simplicity and efficiency of their HemogloBind™ sample preparation technology for removing analytical interferences, in the measurements of total urine protein, and western blot respectively.

The first citation is:

Juriasingani, Smriti, et al. "Evaluating the Effects of Subnormothermic Perfusion with AP39 in a Novel Blood-Free Model of Ex Vivo Kidney Preservation and Reperfusion (https://www.mdpi.com/1422-0067/22/13/7180/htm)." International Journal of Molecular Sciences 22.13 (2021): 7180.

This study evaluated whether adding hydrogen sulfide donor AP39 to Hemopure, a blood substitute, during subnormothermic perfusion improves kidney outcomes. Because of the added Hemopure, the article states, "Most of the urine samples collected were heavily pigmented, due to the presence of hemoglobin …. A 1:3 dilution of urine in HemogloBind allowed us to obtain clearer urine samples …." The investigation concluded that subnormothermic perfusion at 21 °C with Hemopure + 200 nM AP39 improves renal outcomes.

The second citation is:

D'Alessandro, Angelo, et al. "Hematologic and systemic metabolic alterations due to Mediterranean type II G6PD deficiency in a novel murine model (https://www.biorxiv.org/content/10.1101/2021.05.31.446353...)." bioRxiv (2021).

Deficiency of Glucose 6 phosphate dehydrogenase (G6PD) is the single most common enzymopathy and is associated with many diseases. To generate a more accurate model of deficiency, the human sequence for a severe form of G6PD deficiency (Med -) was knocked into the murine G6PD locus. The article states "Briefly, RBCs were washed 3 times PBS, followed by transfer of one part washed RBCs into three parts water, …. Lysed RBCs were then mixed 1:1 with HemogloBind, … to an additional hemoglobin depletion with HemogloBind. Supernatants were used for western blotting." The authors' findings both establish a new mouse model of G6PD deficiency that more accurately reflects human G6PD deficiency.

"The large amount of hemoglobin in many samples presents a special challenge for quantitative analysis. These two articles illustrate the versatility of HemogloBind™ to reduce the interference associated with large concentrations of hemoglobin, without compromising the recovery and analysis of the protein(s) of interest." states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
