Alkali Scientific Blue Dye 20mL (Sterile) 20mL Vial, 10/Pk
Blue Dye, 20mL Sterile Vial, 10/Pk is a ready to use visualization solution designed to support aseptic process simulations, media fill trials, and operator qualification in controlled laboratory and cleanroom environments. The vivid blue coloration provides clear visual tracking of fluid movement, helping operators observe transfer accuracy and procedural performance during training and validation workflows. Packaged in sterile 20mL vials, the solution is suitable for use in pharmaceutical, biotechnology, and GMP regulated facilities where contamination control and process verification are essential. The dye enables realistic simulation of liquid handling without introducing microbial risk, making it a practical tool for validating aseptic technique, equipment setup, and fluid transfer procedures in quality assurance and cleanroom operations.
ILEX LIFE SCIENCES LLC Biocolor Fastin Elastin Dye Reagent, Component, 3 x 110 ml
The Biocolor Fastin™ Elastin Assay is a quantitative colorimetric dye-binding method for the analysis of elastins released into tissue culture medium and extracted from biological materials. The dye label employed is 5,10,15,20-tetraphenyl-21H,23H-porphine tetra-sulfonate (TPPS). Elastin forms that can be measured as α-elastin: soluble tropoelastins, lathyrogenic elastins, insoluble elastins (following solubilization to elastin polypeptides [α-elastin, κ-elastin]). In vitro application: soluble elastin secreted into cell culture medium may be measured directly. Samples should be free from particulate material. Tropoelastin is the elastin form usually found in cell-culture medium during in vitro cell culture. In vivo application: an extraction method of insoluble elastin from tissue and conversion to soluble α-elastin or soluble κ-elastin is given. After solubilization the samples are assayed by the procedure described for soluble elastin. Sensitivity: 5 µg. Assay Time: 4 hours.

Electron Microscopy Sciences Blue Tissue Marking Dye Refill 8 OZ
Fast drying dye is ideal for marking tissue biopsies and pathology specimens and can be used with frozen or fixed tissues. It is a specially formulated binding pigment that evenly coats the tissue without penetrating the tissue surface. The marking dyes do not interfere with diagnostic interpretation due to the fact colors are not similar to standard histopathology dyes. It can be used to permanently mark the margins of excised surgical specimens for exact orientation.

ILEX LIFE SCIENCES LLC Biocolor Blyscan Glycosaminoglycan (sGAG) Dye Reagent, Component, 3 x 110 ml
The Biocolor Blyscan™ Glycosaminoglycan Assay is a quantitative colorimetric dye-binding method for the analysis of sulfated proteoglycans and glycosaminoglycans (sGAG). The assay can be used to measure the total sGAG content and can also be adopted to determine the O- and N-sulfated glycosaminoglycan ratio within test samples. The dye label used in the assay is 1,9-dimethylmethylene blue and the dye is employed under conditions that provide a specific label for the sulfated polysaccharide component of proteoglycans or the protein free sulfated glycosaminoglycan chains. Applications: Cell culture derived material, soluble sGAGs from fluids (ex. synovial fluid, urine), fibrous and hyaline cartilages, tissues (ex. arteries, heart, lung, skin and other material containing extracellular matrix, tumors). Soluble sGAGs may be assayed directly, solid materials will require a preliminary papain extraction. Sensitivity: 0.5 µg. Assay run time: 1 hour.
Newcomer Supply Carbol Fuchsin Stain, Ziehl-Neelsen, 500 ml for AFB Staining
Newcomer Supply Carbol Fuchsin Stain, Ziehl-Neelsen, a crucial element in the Acid Fast Bacteria Stain, Ziehl-Neelsen is used to demonstrate the presence of acid-fast mycobacteria in tissue sections. Acid-fastness is a physical property of certain bacteria and cellular structures. Carbol Fuchsin Stain, Ziehl-Neelsen, combines phenol and basic fuchsin that works to permeate the lipoid capsule of acid-fast organisms and renders them resistant to acid alcohol decolorization. This product has applications for both the Ziehl-Neelsen and Fite AFB staining procedures. Shelf Life is 2 years from date of manufacture. Store at 15-30°C.
