Product name:Spermidine Other name:N-(3-Aminopropyl)-1,4-butanediamine;Spermidin , eN-(3-Aminopropyl)-1,4- butanediamine;4-azaocta , methylenediamine CAS Number:124-20-9 Molecular formula:C7H22N3 Molecular weight:148.29 Purity 5% with 95% Silicon Oxygen( or wheat germ extract ) Appearance:White crystalline powder Packing 1 kg/bag , 25kg/drum Application:Dietary supplement material 3Product introduction Spermidine, a low molecular weight aliphatic carbide containing 3 amine groups, is one of the natural polyamines present in all living organisms. One of the important raw materials for drug synthesis is widely used in the synthesis of pharmaceutical intermediates. Spermidine maintains cell membrane stability, increases antioxidant enzyme activity, and improves photosystem II (PSII) and related gene expression. Spermidine also significantly reduced H2O2 and O2.- levels. Spermidine is a precursor of spermidine, derived from putrescine, which promotes the structural stability of cell membranes and nucleic acids. Spermidine has a variety of amazing effects, including but not limited to regulating circadian rhythm, improving hypertension, protecting cardiovascular, preventing Alzheimer's, boosting immunity, fighting cancer and even anti-aging... 4Feature Spermidine is a naturally occurring polyamine compound commonly found in food. It is essential for cell growth and survival. Spermidine maintains cell membrane stability, increases antioxidant enzyme activity, and improves photosystem II (PSII) and related gene expression. Spermidine also significantly reduced H2O2 and O2.- levels. Colorless transparent liquid, soluble in water, alcohol and ether; It is hygroscopic. The low purity format spermidine is available in 1% ,5%,20% etc. 5Applications Spermidine is involved in many biological processes in vivo, such as regulating cell proliferation, cell aging, organ development, immunity, cancer and other physiological and pathological processes. Recent studies have shown that spermidine plays an important role in regulating synaptic plasticity, oxidative stress and autophagy in the nervous system. Spermidine can slow protein aging. Because different molecular weight proteins may play different roles in the aging process, some large molecular weight proteins may play a key role in controlling the aging process of leaves. Once these proteins begin to degrade, aging is inevitable, and controlling the degradation of these proteins can delay the aging process.

Sodium heparin Content:
[Product Name] Sodium heparin  [Package Specification] Plastic bottle, 10g/bottle, 20g/bottle, 50g/bottle [Product Standard] Q/WHDS 003-2016 [Product Performance] White amorphous powder, odorless, soluble in water, easy to absorb moisture, average molecular weight of 15,000, stable at room temperature. The potency of sodium heparin of our company is ≥150 IU/Mg, and the potency of anhydrous sodium heparin is ≥ 160 IU/Mg. Other indexes were controlled according to sodium heparin standard.  [Scope of application] 1. This product is applicable to the collection and anticoagulation of blood samples for clinical biochemical examination and emergency biochemical examination, and also applicable to the collection and anticoagulation of blood samples for some hemorheology projects.   2. The use of sodium heparin as an anticoagulant is recommended for the determination of ion content in blood in clinical tests because it is the least likely to interfere with the determination of other ions.   3. This product is not a drug and cannot be used as an injection. Direct injection into human body and animals is prohibited. [Precautions] In order to ensure sufficient anti-coagulation of blood, it is necessary to mix the blood upside down for 5-8 times as soon as possible after the completion of blood collection, especially when the ambient temperature of blood collection is higher than 25℃, the mixing of blood and  sodium heparin must be sufficient in time, otherwise it is easy to cause blood coagulation or local coagulation. Heparin anti-coagulation is not irreversible, so the test should be completed within 6 hours after blood collection in heparin anti-coagulation test tube, otherwise the test results may have errors. Heparin may be involved in the metabolism of cell enzymes and ions, so the use of heparin may affect the test results. The dosage of heparin should ensure the full anti-coagulation of the whole and local samples, so as to ensure that most of the plasma indexes can be repeated within 6 hours, especially the sensitive indexes such as AST, ALT, TBIL, DBIL and GGT. Sodium heparin can be used at the same time with the separation gel. Anticoagulant effect, tube wall silicification, centrifugation conditions, separation gel quality and so on will affect the blood separation effect. It is suggested that high quality plasma samples can be obtained by using the blood separation gel produced by our company. It is recommended to use γ - ray irradiation at a dose of 8-25kgy. The irradiation dose can be determined by the initial colony number. [Warning and Prevention] It is forbidden to use sodium heparin when it has impurities, abnormal smell, color and expiration date. When the sodium heparin solution appears turbid, it may be that the heparin solution has been contaminated with bacteria or deteriorated, please do not continue to use. This product is a biological preparation, safe, non-toxic and harmless. [Storage conditions]  The product can be sealed and stored in a cool and dry place, away from light and moisture. The aqueous solution of this product can be sealed at 0-4℃ in sterile state, and the longest storage period shall not exceed 7 days. It is recommended that the aqueous solution of this product be prepared and used immediately, and not stored in solution state for a long time. [Validity] 3 years Desheng is an established blood test reagent company with 14 years of R&D and production experience. It has a lot of research on blood collection additives.
