Histopaque®, sterile filtered, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

ACCUSPIN System-Histopaque-1077 products are intended for use in the isolation of lymphocytes and other mononuclear cells. The separation medium, Histopaque-1077, is a sterile-filtered, endotoxin-tested solution of polysucrose and sodium diatrizoate, adjusted to a density of 1,077 g/ml. ACCUSPIN System-HISTOPAQUE-1077 employs γ-irradiated 50 mL polypropylene centrifuge tubes specially designed with two chambers separated by a porous high-density polyethylene barrier ('frit'). Each tube is aseptically filled with 15 ml of Histopaque 1077. Each tube will separate 15-30 mL of anticoagulated blood.

Tetrabromophenol blue, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Tetrabromophenol Blue (TBPB) belongs to the group of sulfonephthalein acid-base indicators. It is employed in the potentiometric titration of the halogens with Hg₂(NO₃)₂. In addition, it has been used as a dye indicator in urine dipstick test to detect proteinuria. In this assay, with increasing concentration of urinary protein, TBPB sequentially changes colour from pale green to blue. Binding of TBPB to proteins is dependent on pH.
