An internal standard for the quantification of creatinine by GC- or LC-MS.

Oxidized low-density lipoprotein (oxLDL) particles contain low molecular weight species which promote the differentiation of monocytes and activate PMNL. Many of these substances were recently isolated and purified from oxLDL, and identified as phosphatidylcholine species containing a fragmented,…

Naturally occuring mycotoxin and food contaminant that induces the transversion of G to T at codon 249 of the p53 tumor suppressor gene and is a likely pathogen that causes hepatocellular carcinoma.

SKF 38393 is a partial agonist of the dopamine D₁-like receptors D₁ and D₅ (K_is = 1 and ~0.5 nM, respectively). It less potently binds D₂, D₃, and D₄ receptors (K_is = ~150, 5,000, and 1,000 nM, respectively).

Sodium chloride stock solution contains filtered sodium chloride (5 M). It is ready to use as supplied.

A RAR antagonist with moderate selectivity for RARβ over RARα (Kis = 0.22 and 1.4 μM, respectively); inhibits retinoid Am80-induced differentiatiobn of HL-60 cells (IC₅₀ = 0.2 μM).

10-Pyrene-PC is a substrate for all PLA2s with the exception of cPLA2 and PAF-AH. Upon phospholipid hydrolysis, 10-pyrenyldecanoic acid is produced from 10-pyrene-PC. The monomeric 10-pyrenyldecanoic acid exhibits fluorescence (excitation 345 nm, emission 395 nm), allowing quantitation of…

A natural demethoxy derivative of curcumin; activates macrophage phagocytosis and, with 1α,25-dihydroxyvitamin D3, stimulates amyloid-β clearance by macrophages (optimal stimulation at 100 nM BDMC); suppresses proliferation in cancer cells; down-regulates p300 and inhibits LPS-induced…

Magnesium chloride stock solution contains filtered magnesium chloride (1 M). It is ready to use as supplied.

A cell-permeable, fluorescent probe for DNA (ex. 352 nm/em. max 461 nm) that is useful as a marker of nuclei for cell cycle and to distinguish nuclear morphology in apoptotic cells.

An inhibitor of ALK5, ALK4, and ALK7 (IC₅₀s = 12, 45, and 7.5 nM, respectively); blocks the phosphorylation of Smad2/3 and inhibits TGF-β-induced epithelial-to-mesenchymal transition; used to reprogram fibroblasts into alternative lineages.

An endogenous agonist for LXRα (EC₅₀ = 325 nM) that can induce the expression of the ABCA1 reverse cholesterol transporter to inhibit the overall absorption of cholesterol; used as a substrate to monitor cholesterol transport or as an endogenous positive control for testing LXR agonists.
