Scytek Laboratories HEMATOXYLIN, MAYER'S, 1 L

Mayer's Hematoxylin (Lillie's Modification) is a progressive nuclear hematoxylin stain with several histological applications. Nuclei should staining is strong, clean, crisp, and no differentiation is needed. Bluing reagent (Catalog: BRT) may be used following hematoxylin to ""blue"" or alter the shade of hematoxylin from a purple to blue. Nuclei: Purple. Nuclei after Bluing: Blue. Blue nuclei after Eosin: Blue to Violet.Hematoxylin is a nuclear stain that is used as a counterstain for immunohistochemistry (IHC). Together with eosin, it forms the Hematoxylin and Eosin stain (H&E stain), one of the most commonly used stains in histology.Summary Protocol:Apply Hematoxylin to completely cover specimen and incubate for 2-10 minutes with hematoxylin according to desired intensity.

Biotium Calcein AM, 1 mg/mL in Anhydrous DMSO

Calcein AM is a widely used green fluorescent cell marker. Calcein AM is membrane-permeant and thus can be introduced into cells via incubation. Once inside the cells, calcein AM is hydrolyzed by endogenous esterase into the highly negatively charged green fluorescent calcein, which is retained in the cytoplasm. Calcein AM is an excellent tool for the studies of cell membrane integrity and for cell tracing. Supplied in lyophilized form or as a solution in anhydrous DMSO at 4 mM (80011-1) or 1 mg/mL (1 mM) (80011-2). Calcein AM is also offered in our Cell Viability and Cytotoxicity Assay Kit. Properties: Ex/Em (calcein) = 494/517 nm (pH 8); Colorless solid soluble in DMSO; Store at -20°C and protect from light; C46H46N2O23; MW: 995

Bioworld Safranin-O-Counterstain, 500 mL

Safranin O is a biological stain commonly used as a counter stain for gram-negative bacteria in the Gram stain procedure. Safranin O has been observed to bind to DNA at a pH 2.21. In the Flemming triple stain procedure Safranin O is used to stain for chromosomes. In late Palaeozoic pteridosperm cuticlesSafranin Ohas shown increased contrast, emphasized cutinization differences, and enhanced the three-dimensional morphology of complex epidermal features when compared with other dyes. The compound has also been used with alcian blue in the histochemical study of the distribution and morphometric characteristics of mast cells.Safranin Ohas also been used to detect mucin and cartilage.

Ethos Biosciences Gram Stain, Decolorizer 75/25, 4x16oz, Ethos

75/25 Gram Decolorizer is a solvent blend designed for microbiology and general laboratory applications. Used as the decolorizing step in Gram staining procedures, it selectively removes the primary stain from gram-negative organisms while allowing gram-positive organisms to retain the crystal violet–iodine complex. The controlled 75/25 formulation provides consistent and reliable decolorization for accurate differentiation during microscopic evaluation. Ideal for routine diagnostic and research workflows, it supports dependable and reproducible Gram stain results. Supplied in chemically compatible containers, 75/25 Gram Decolorizer is suitable for clinical, research, and educational laboratory environments.

Ethos Biosciences AFB Kinyoun Carbol Fuchsin Replacement Kit, 4x8oz, Ethos

AFB Kinyoun Carbol Fuchsin is formulated for use as the primary stain in acid-fast staining procedures, including the Kinyoun “cold” method. It penetrates the waxy cell walls of acid-fast organisms, producing a strong red coloration that resists decolorization with acid-alcohol. This allows clear differentiation of acid-fast bacteria from non–acid-fast material after application of a suitable counterstain. Suitable for routine use in clinical, veterinary, and research laboratories, the reagent is compatible with standard acid-fast staining protocols and manual procedures. The formulation supports consistent staining performance and dependable results in microbiology applications.

Biotium SynaptoRed™C1

SynaptoRed™ C1 is similar to the widely used red fluorescent nerve terminal dye SynaptoRed™ C2 (also called FM4-64) except that the lipophilic tail of SynaptoRed™ C1 is one carbon shorter than that of the SynaptoRed™ C2. Thus, SynaptoRed™ C1 is expected to have a faster off-rate compared to SynaptoRed™ C2. Properties: Dark purple solid soluble in water; C28H41Br2N3; MW: 580

Biotium Lumitein™ PROTEIN GEL STAIN, 100X

Lumitein™ is a luminescent dye designed for detecting proteins in SDS polyacrylamide (SDS-PAGE) gels, but that can also be used to detect proteins in native PAGE gels after an additional SDS incubation step. It is as sensitive as the best silver stain by detecting 1 ng or less protein. Unlike silver stain, however, Lumitein™ has a linear detection range of at least 3 orders of magnitude. Gels can be stained in 90 minutes or less without a separate fixation step. Lumitein™ has an excitation spectrum that makes detection possible with either a simple UV box or fluorescence laser scanner. Moreover, protein gel staining with Lumitein™ is compatible with downstream protein analyses such as mass spectrometry and Edman-based sequencing.
