Fura-2 AM
Artikelnummer: Cay14591-1
Fura-2 AM is a noninvasive, intracellular calcium indicator that is UV light-excitable. This AM ester form crosses cell membranes and once inside the cell is converted by cellular esterases to fura-2, the pentacarboxylate calcium indicator. The spectral properties of fura-2 in the presence of low calcium concentrations (excitation max = 362 nm, emission max = 512 nm) differ...

Dehydroepiandrosterone
Artikelnummer: Cay15728-1
Dehydroepiandrosterone (DHEA) is an endogenous steroid hormone that is secreted primarily by the adrenal gland and is the most abundant sex steroid. Metabolites of DHEA include androstenedione (Cay-ISO60161), which subsequently may be metabolized to testosterone (Cay-ISO60154, Cay-15645) or estrone (Cay-ISO60165, Cay-10006485) which is an estradiol (Cay-ISO60155,...

Sodium Dodecyl Sulfate (SDS), pure
Artikelnummer: 04051.1
SDS is commonly used in the preparation of proteins for electrophoresis in SDS-PAGE. This compound works by disrupting non-covalent bonds in proteins, denaturing them and causing the proteins to lose their natural conformation. The new negative charge is significantly larger than the original charge of that protein. The electrostatic repulsion generated by the binding of SDS...
