| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Purification and characterization of stachyose synthase from lentil (Lens culinaris) seeds: galactopinitol and stachyose synthesis.[Pubmed:10334866]
Arch Biochem Biophys. 1999 Jun 1;366(1):75-81.
Stachyose synthase (STS) (EC 2.4.1.67) was purified 313-fold from mature seeds of lentil. The final preparation had a specific activity of 9.09 nkat stachyose formed per milligram of protein. The enzyme was a monomeric protein with a molecular mass of 88.6 kDa (SDS-PAGE) and an isoelectric point of 4.8 (chromatofocusing). Western analysis revealed cross-reactivity of polyclonal antibodies raised against STS from adzuki bean with the lentil enzyme. The purified enzyme catalyzed a range of different galactosyl transfer reactions. In addition to the genuine STS reaction (raffinose + galactinol --> stachyose + myo-inositol), the enzyme catalyzed the reversible galactosyl transfer from galactinol to d-pinitol (1d-3-O-methyl-chiro-inositol), yielding Galactopinitol A (O-alpha-d-galactopyranosyl-(1 --> 2)-4-O-methyl-d-chiro-inositol) and myo-inositol. Galactopinitol A could be further galactosylated by STS to give ciceritol (O-alpha-d-galactopyranosyl-(1 --> 6)-O-alpha-d-galactopyranosyl-(1 --> 2)-4-O-methyl-d-chiro-inositol). Enzymatic synthesis of Galactopinitol A and ciceritol is a new observation. However, STS was not only able to utilize Galactopinitol A as galactosyl acceptor, but also as galactosyl donor to form stachyose from raffinose. The role of STS in the metabolism of galactosyl cyclitols and oligosaccharides in plant seeds is discussed.
