Two Research Articles Cite HemogloBind™ to Remove Analytical Interference from Hemoglobin
MONMOUTH JUNCTION, NJ, October 17, 2023 -- Biotech Support Group reports on two journal articles describing the simplicity and efficiency of HemogloBind™, to remove Hemoglobin interferences prior to analysis. The first citation is: Kaneko, Tomonori, et al. "Kinome and phosphoproteome reprogramming underlies the aberrant immune responses in critically ill COVID-19 patients." (2023). The SARS-CoV-2 infection elicits comprehensive host immune reactions and causes severe diseases in some individuals. However, the molecular basis underlying the excessive, yet non-productive immune responses in severe COVID-19 is not fully understood. To address this, we compared the peripheral blood mononuclear cell (PBMC) proteome and phosphoproteome of sepsis patients positive or negative for SARS-CoV-2 and healthy subjects by quantitative mass spectrometry. The article states “For Sample processing for proteomics by mass spectrometry,… Hemoglobin was depleted from PBMC whole cell lysate samples according to HemogloBind (Biotech Support Group LLC) manufacturer instruction …” The report shows that COVID-19 PBMC proteome and phosphoproteome undergo dynamic changes during disease progression, and the corresponding protein or phosphoprotein signatures can distinguish longitudinal disease states. Furthermore, SARS-CoV-2 infection leads to a global reprogramming of the kinome and the phosphoproteome, resulting in defective adaptive immune response mediated by B and T lymphocytes, compromised innate immune responses involving the SIGLEC and SLAM family of immunoreceptors, and excessive cytokine-JAK-STAT signaling. The second citation is: Dugbartey, George J., et al. "Static cold storage with mitochondria-targeted hydrogen sulfide donor improves renal graft function in an ex vivo porcine model of controlled donation-after-cardiac-death kidney transplantation." International Journal of Molecular Sciences 24.18 (2023): 14017.
The
global donor kidney shortage crisis has necessitated the use of
suboptimal kidneys from donors-after-cardiac-death (DCD). Using an ex
vivo porcine model of DCD kidney transplantation, the present study
investigates whether the addition of hydrogen sulfide donor, AP39, to
University of Wisconsin (UW) solution improves graft quality. Urine
and arterial blood samples were collected hourly during reperfusion.
The article states “Urine protein levels were measured using an
IDEXX Urine Analyzer (IDEXX Laboratories, Westbook, ME, USA)
following a 1:3 dilution of urine in HemogloBind (Biotech Support
Group, Monmouth Junction, NJ, USA) to obtain clearer urine samples
after 10 min of vigorous shaking and centrifugation at 12,000× g.”.
The observations indicate significant increases in urine production
and blood flow rate, and reduced levels of urine protein, serum
creatinine, blood urea nitrogen, plasma Na+ and K+ , as well as
reduced intrarenal resistance in the UW+AP39 group compared to the
UW-only group. Histologically, AP39 preserved renal structure by
reducing the apoptosis of renal tubular cells and immune cell
infiltration. The finding could lay the foundation for improved graft
preservation and reduce the increasingly poor outcomes associated
with DCD kidney transplantation.
