Growth Hormone (GH) is a 23 kDa circulating pituitary hormone, Rat GH shares approximately 97% homology with mouse GH and 65% homology with human GH in its protein sequence.

GIP, also known as gastric inhibitory polypeptide, or glucose-dependent insulinotropic polypeptide, is a 42 amino acid peptide hormone synthesized in and secreted from K cells in the intestinal epithelium.

Insulin, a 5.8 kDa hormone, is secreted by the islet beta cells in the pancreas.

The OxyELISA™ Oxidized Protein Quantitation Kit provides a sensitive methodology for detection and quantitation of proteins modified by oxygen free radicals and other reactive species. Oxygen-derived free radicals have been implicated in numerous physiological functions such as apoptosis, cancer, aging, neurodegenerative diseases, chronic inflammatory diseases, pulmonary diseases, and cardiovascular diseases (for reviews, see…

TMB, (3,3',5,5'-tetramethybenzidine) has been shown to be a safe-sensitive substrate for the assay of HRP. Initially, in the presence of HRP and hydrogen peroxide, a one-electron oxidation product is formed. This compound, a cation free radical, is blue in color with an adsorption maximum of 653 nm. Further reaction with HRP/H2O2 or acidification of the radical with acid yields the diimine terminal oxidation product adsorbing…

Antipain is a serine and cysteine reversible protease inhibitor. It inhibits papain and trypsin. Plasmin is inhibited to a small extent as well. More specific than leupeptin for papain and trypsin. Source: Microbial origin. Not synthetically made.

Sterivex filter units work with syringes, peristaltic pumps or pressure vessels. They eliminate the risk of contamination associated with decanting or pipetting.Sterivex units are designed to dispense into virtually any storage container. The devices are available with different outlet connectionsSterivex filter units can process volumes up to 1,000 mL or 2,000 mL, depending on the type of membrane used in the device. A choice…

Steripak-GP filter units are designed for larger scale pressure-driven filtration of tissue culture media with or without serum. They are single use and are not autoclavable. The filter units come in two sizes, with the smaller unit able to filter up to 10 L and the larger up to 20 L. Both sizes utilize the low protein binding, fast flow 0.22 µm EMD Millipore Express membrane.

The Steriflip filter unit is designed to work with standard 50 mL centrifuge tubes, which eliminates sample transfer. To filter, just attach the unit to a 50 mL centrifuge tube containing your sample, flip it over, and apply the vacuum. When finished, the filtrate collects in the attached 50 mL centrifuge tube.Steriflip Nylon Net filters are now available in 40, 60 and 100 µm pore sizes, making them ideal for stem cell, cardio…

Steritop bottle top filter units provide a large filter area for rapid sterile filtration of aqueous fluids into narrow-mouth (33 mm) or wide-mouth (45 mm) bottles. A small tab inside the funnel secures an optional prefilter in-place during filtration. For added protection against contamination, the threads for bottle attachment have been slightly recessed in case the funnel accidentally touches a work surface

Sterivac vacuum-driven filter units are ideal for bottle-top filtering directly into receiver flasks at flow rates as fast as 1.5 L/min. The unique "start & stop" filtration action makes setting up, filtering and transferring the unit to another receiver fast and easy. Push a button to stop filtering, move the device to an empty bottle and restart

The Stericap ™ PLUS Universal Bottle-Top Filter Device provides fast, large-volume filtration into any sized bottle.
