Newcomer Supply PAP GnomePen Classic Liquid Blocker, Blue
PAP GnomePen liquid blocker is a proprietary formulation that is applied around the tissue sections on a microscope slide prior to immunohistochemistry. It dries in less than one minute! PAP GnomePen Liquid Blocker creates a thin visible hydrophobic film around tissue sections to reduce the amount of reagent needed for tissue coverage and stain reaction. GnomePen has one of the thinnest PAP pen tips available, allowing for adjacent circles, lines or a drawn pattern to be applied on a single slide. GnomePen contains a unique formulation that is water repellent, insoluble in alcohol and acetone, soluble in xylene and is insensitive to detergents (Triton X-100, Tween 20), varying pH and temperature. The GnomePen Classic PAP Pen is optimized for tissue sections between 4-20 microns thick. Estimated coverage would be for approximately 350 slides. Also available in Red, Green, Orange, Violet and Yellow.
Electron Microscopy Sciences Aurion Cold Water Fish Skin Gelatine 40% 10 ML
The use of Cold Water Fish Skin Gelatin to prevent background reactions has been recommended by e.g. Behnke et al. (J. Cell Biol. 41, [1986], 386). The product is supplied as a liquid concentrate (40%).
Electron Microscopy Sciences Aurion Blocking Solution Goat 30 ML
Aurion has developed Blocking Solutions which effectively block ‘sticky' surfaces by multi-point hydrophobic and charge-based interactions. The Blocking Solutions are specifically designed to meet the characteristics of each type of secondary conjugate. With adequate blocking and incubation media, background reactions are minimized whereas specific reactions are not hampered.
Biocare Medical, LLC PeroxAbolish - 500 ml
PeroxAbolish is a novel formula that is a non-hydrogen peroxide blocking reagent that is safe and extremely gentle on tissues and cells. It is highly effective in quenching endogenous peroxidase and can be used on formalin-fixed paraffin-embedded tissues, cell culture, blood smears, cell preparations and frozen sections. When using paraffin-embedded formalin-fixed tissues, PeroxAbolish is extremely effective after antigen retrieval methods. It can also be used on an automated staining system.
Vector Laboratories Vector TrueVIEW Autofluorescence Quenching Kit, 15ml
The TrueVIEW Autofluorescence Quenching Kit provides a novel way to diminish unwanted autofluorescence from non-lipofuscin sources and dramatically improve signal-to-noise ratio. TrueVIEW removes unwanted autofluorescence in tissue sections due to aldehyde fixation, the presence of red blood cells, and structural elements such as collagen and elastin. The quenching action of the kit reagents provides a clear, unambiguous, “true view” localization of the target antigen.
Biocare Medical, LLC Background Eraser
Background Eraser is specifically formulated for superior pH stability and designed to reduce nonspecific background staining often found with immunohistochemistry techniques. It is optimized to work with Biocare 4plus detection systems and is only used when secondary antibodies are derived in goat. It can also be used on an automated staining system.
Biocare Medical, LLC Background Punisher - 500 ml
Background Punisher is a universal blocking reagent used for reducing nonspecific background staining often found with immunohistochemistry. Background Punisher is specifically formulated for superior pH stability and is sodium azide and thimerosal free. It can be used with automated or manual staining protocols.
