Dextran sulfates are supplied as the sodium salt forms that are soluble and stable in water. It consist of 17% (approx.) sulfur equivalent to 2.3 (approx.) sulfate groups per glucosyl residue. Dextran is a (complex branched glucan) polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(166) linkages and the remaining (163) linkages account for the branching of dextran.

Dextran sulfate is an anionic polymer of sulfated glucose, capable of accelerating hybridization rates of nucleic acids. The polyanionic character of Dextran sulfate helps to approximate nucleic acid strands, increasing their effective concentration to each other and promoting hybridization. Dextran sulfate also demonstrates a sequestering interaction with proteins, presumably through hydrogen-bonding between the sulfate groups and amine groups of the protein that generates an insoluble complex. The ability of the polymer to precipitate fibrinogen and low-density lipoproteins from plasma solutions has been used for analysis and for anticoagulant applications.

Used for the detection of DNA or RNA in nucleic acid hybridization procedures. It effectively "excludes" probe from solution, accelerating the rate of annealing.

Human Growth Peptides IGF-1 IGF1 Human Des1-3
IGF-1 Basic Info.
Product Name: IGF1 Human Des1-3 (IGF-1)
Molar Mass: 7,372 Da
Synonyms: IGF-1Des(1-3); Des1-3; Des 1-3; Des (1-3)
Compound: Thr-Leu-Cys-Gly-Ala.
Purity: 99.21%
IGF-1 IGF-1DES Dose:
DES IGF-1 can be dosed at 50-150mcg multiple times a day (prior to training) into specific target areas. since DES has such a short half life (20-30 minutes), desensitization was not noticed at all . Injection sites should be localized; preferably, at the muscle group you want to grow. In simple terms, if you want to grow your biceps, inject IGF-1DES right into your bicep.
IGF-1 IGF-1DES Half-life:
DES IGF-1 is the shorter version of the IGF-1 chain. It is five (5) times more powerful than IGF-1LR3 and ten (10) times more powerful than regular base IGF-1. The half-life for DES is about 20-30 minutes, which means this is a very delicate chain. Therefore, administration should only be done at the site where you want to see muscle growth. DES has the ability to stimulate muscle hyperplasia better than LR3. In simple terms, it's best used for site injections, rather than overall growth.
In addition, DES is known to bind to receptors that have been deformed by lactic acid, which is often present during workouts. This allows the DES to attach itself to a mutated receptor and signal tissue growth during training. DES can be used longer and more frequently than LR3.
