Medchemexpress LLC Sucralose | 56038-13-2 | 397.63 | 50 MG
Sucralose (Standard) is the analytical standard of Sucralose, intended for research and analytical applications. It is a non-nutritive artificial sweetener and sugar substitute (E955; Trichlorosucrose). This compound can activate a conserved neural fasting response, leading to an appetite-stimulating effect in rodents. It is commonly used in qualitative, quantitative, and methodological research experiments in HPLC, GC, and MS.

Cayman Chemical Derythro Lysosphingomyelin d
A bioactive sphingolipid; agonist of S1P1, S1P2, and S1P3 (EC50s = 167.7, 368.1, and 482.6 nM, respectively, for the human receptors); agonist of ORG1 that induces calcium accumulation in cells overexpressing OGR1 (EC50 = ~35 nM); levels are increased in skin isolated from patients with atopic dermatitis, as well as postmortem brain from patients with Niemann-Pick disease type A
Gold Biotechnology Inc HEPES, Free Acid 500 g
HEPES is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.8 – 8.2. HEPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in solutions with metal ions. It is commonly used in cell culture media and as an ampholytic separator to create a pH gradient in isoelectric focusing. HEPES interferes with reactions between DNA and restriction enzymes to a lesser extent than similar buffers with less substituted amine groups, such as Tris. This lack of interference occurs because steric hindrance of the protonated tertiary amine in HEPES shields the negative charge of DNA to a lesser extent than less substituted buffers. This buffer is capable of forming radicals and is therefore not suitable for redox reactions. It is suitable for use in the bicinchoninic acid (BCA) assay.
Gold Biotechnology Inc X-?-Gal 250 mg
X-α-Gal is a chromogenic substrate for α-galactosidase, yielding a blue precipitate. X-α-Gal is used for detecting two-hybrid interactions directly on the culture media. This substrate eliminates the need for β-galactosidase liquid and filter-lift assays in two-hybrid analysis.
Gold Biotechnology Inc X-Gal 1 g
5-Bromo-4-chloro-3-indolyl β-D-galactopyranoside is most commonly known as X-Gal. X-gal is a histochemical substrate for β-galactosidase which cleaves X-Gal to yield an insoluble blue precipitate.
