Sigma Aldrich Fine Chemicals Biosciences Apolipoprotein E4 human re
Apolipoprotein E (ApoE) is present in the brain and is mainly produced by astrocytes. It is a 299 amino acid glycoprotein of 34kDa. It is present in all classes of lipoproteins except LDL (low-density lipoprotein). APOEnbspgene has three alleles such as APOEnbspε3 APOEnbspε4nbspand APOEnbspε2. It is located on human chromosome 19q13.

Cayman Chemical Cholesterol Sulfate (sodium salt), Purity: ≥95%, CAS: 2864-50-8, 100 mg
An endogenous component of cell membranes where it serves as a substrate for steroid synthesis, influences lipid metabolism, stabilizes cell membranes, regulates the activity of functional proteins, and plays a role in keratinocyte differentiation and development of the epidermal barrier
Cayman Chemical DL-Homocysteine, Purity: ≥90%, CAS: 454-29-5, 500 mg
An amino acid; inhibits ACh-induced vasodilation of precontracted isolated guinea pig pulmonary artery rings and enhances phenylephrine-induced contraction of isolated guinea pig pulmonary artery rings; inhibits endothelium-dependent ACh-induced vasodilation in the vascular bed of isolated perfused rat pancreas at 200 µM; elevated plasma levels are positively correlated with occlusive arterial diseases and atherosclerosis
Cayman Chemical 7-dehydro Cholesterol, Purity: ≥90%, CAS: 434-16-2, 5 g
An immediate precursor to cholesterol; accumulates in Smith-Lemli-Opitz syndrome (SLOS); highly susceptible to free radical oxidation, giving rise to several oxysterols that may be involved in the pathogenesis of SLOS; levels are increased in brain, liver, and serum in a rat model of SLOS induced by the DHCR7 inhibitor AY 9944; converted to vitamin D3 by UVB light ex vivo
Cayman Chemical 19-hydroxy Cholesterol, Purity: ≥98%, CAS: 561-63-7, 10 mg
An oxysterol formed during the metabolic oxidation of cholesterol; used as an internal standard for the quantitative determination of sterols by mass spectroscopic analysis
Cayman Chemical Palmitoyl Serotonin, Purity: ≥98%, CAS: 212707-51-2, 10 mg
A hybrid molecule patterned after N-arachidonoyl serotonin; while saturated 11- or 12-carbon fatty acids linked to serotonin potently inhibit capsaicin-induced TRPV1 channel activation (IC50 = 0.76 μM) without blocking FAAH-mediated hydrolysis of arachidonoyl ethanolamine (IC50 > 50 μM), the effects of palmitoyl serotonin are unknown

Apolipoprotein A-I from hu5MG
Cayman Chemical N-(p-Coumaroyl) Serotonin, Purity: ≥95%, CAS: 68573-24-0, 1 mg
An antioxidative phenolic naturally found in plants, including safflower seed and millet grain; ameliorates atherosclerosis in vivo, reducing lesion area in mice and rabbits
Cayman Chemical Docosahexaenoyl Serotonin, Purity: ≥98%, CAS: 283601-58-1, 50 mg
A hybrid molecule patterned after N-arachidonoyl serotonin; effects of docosahexaenoyl serotonin are unknown
