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.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Biochemical and Immunological Characterization of Chalcone Synthase from Rye Leaves.[Reference: WebLink]

Journal of Plant Physiology, 1988, 133(2):178-182.

As part of investigations on the role and the location of the key enzyme of flavonoid biosynthesis, chalcone synthase (CHS) in leaf tissues of Gramineae, CHS from rye (Secale cereale L.) was purified and characterized biochemically and immunologically.
METHODS AND RESULTS:
Km-values for the substrates p-coumaroyl-CoA and caffeoyl-CoA were 0.6 and 1.45 μM, respectively, the corresponding Km-values for malonyl-CoA were 1.4 and 1.5 μM. The pH-optimum for the formation of 2′,4,4′,6′-tetrahydroxychalcone was 8 and for the formation of 2′,3,4,4′,6′-pentahydroxychalcone, 6.5. A 50% reduction in enzyme activity was caused by 9 μM apigenin, 13 μM luteolin, 36 μM CoA, 45 μM naringenin, 45 μM eriodictyol, and 62 μM Isovitexin 2''-O-arabinoside. SDS-PAGE analysis of the purified enzyme revealed two peptides with apparent molecular weights of 43 and 44 kd, respectively.
CONCLUSIONS:
On western blots run with the purified enzyme as well as with crude enzyme extracts, both peptides were immunostained by polyclonal antibodies raised against rye or parsley CHS. The recognition of these peptides by single monoclonal antibodies demonstrated that both peptides were similar and derived from CHS. Applied to western blots run with CHS-containing extracts of parsley, spinach, pea, maize, and oat, the same antibodies labelled only a single peptide, or in some cases probably even more than two peptides.
