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.

Biotium NucSpot Live 488, 1000X in DMSO

NucSpot Live Cell Nuclear Stains are cell-membrane permeable DNA dyes that specifically stain nuclei in live or fixed cells. They have excellent specificity for DNA without the need for a wash step, and they have low toxicity for live cell imaging. The dyes are supplied as 1000X stock solutions in DMSO, and are supplied with a vial of verapamil, which may increase probe retention and staining in some cell types. NucSpot Live 488 stains nuclei with green fluorescence and has an excitation/emission of 500/515 nm. Properties: Ex/Em= 500/515 nm; Store at 4°C and protect from light.

Alkali Scientific Hematoxylin, 100 G

Hematoxylin is a histology stain used primarily for tissue staining in medical and research laboratories. It is often combined with eosin to create the Hematoxylin and Eosin (H&E) staining method, which is widely employed for visualizing tissue structures in histological slides. Hematoxylin stains cell nuclei a dark blue or purple, which provides excellent contrast when examining tissue under a microscope. This 100g package of hematoxylin is ideal for laboratories involved in routine histopathology work, offering a high-quality solution for tissue fixation, staining, and examination. It is a crucial reagent for diagnosing diseases, including cancer, by highlighting cellular and tissue abnormalities.

Alkali Scientific Phenol Red Broth with Dextrose 8mL with Durham Tube, 10/Pk

Phenol Red Broth with Dextrose, 8mL with Durham Tube, 10/Pk is a differential culture medium used to evaluate carbohydrate fermentation and gas production in bacterial species. The medium contains phenol red as a pH indicator and dextrose as the fermentable carbohydrate source. When bacteria ferment dextrose, acid production lowers the pH and changes the color of the medium from red to yellow. Each tube also contains a Durham tube that captures gas produced during fermentation, allowing simultaneous observation of acid and gas formation. The 8mL prepared broth is supplied in 13 x 100mm screw cap tubes for secure handling and contamination control. This medium is widely used in biochemical testing panels for microbial identification in clinical, food safety, and environmental laboratories.
