Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Effects of DL-Alanine and Betaine Supplemented Diets on the Growth and Body Composition of Fingerling Rainbow Trout (Oncorhynchus mykiss, W.1972)[Reference:
WebLink]
METHODS AND RESULTS:
In this study, the effects of feeds supplemented with DL-Alanine and betaine on the growth and chemical composition of fingerling rainbow trout (Oncorhynchus mykiss) were investigated. Fish fed with DL-Alanine (1.5% of diet) and betaine (1.5% of diet) supplemented diets had greater weight gains (35.36 +/-1.81 g and 38.47 +/-3.02 g respectively) than those fed a control diet (28.32 +/-0.31 g). It was found that the groups fed with attractant supplemented diets had better feed conversion and protein efficiency ratios than the control group.
CONCLUSIONS:
Whole body dry matter, fillet and whole body crude ash and crude protein ratios were similar in all the groups. The group fed a DL-Alanine supplemented diet had a higher fillet dry matter ratio than the control group (p<0.05). The group fed a betaine supplemented diet had a lower whole body lipid ratio than control group (p<0.05) and all the groups were found to be similar in terms of fillet lipid ratios.

Mixed ligand complexes of benzimidazole and pyrimidine hydroxy azo dyes with some transition metals and glycine, dl-alanine or dl-leucine.[Reference:
WebLink]
METHODS AND RESULTS:
The overall formation constants of 1:1:1 ternary complexes of Cu(II), Zn(II), Cd(11) with glycine, DL-Alanine or dl-leucine as primary ligands and o-hydroxyphenylyazo derivatives of 2-cyanomethyl benzimidazole (ABI) and barbituric acid (ABA) as secondary ligands have been investigated potentiometrically in 40% (v/v) EtOH. Formation constants of binary systems were also determined under the same experimental conditions (37°C and μ=0.15 mol dm−3). The stability of ternary complexes have been quantitatively compared with those of the corresponding binary complexes in terms of the parameters Δ log K, log X and log X′. The data were interpreted on the basis of statistical considerations and the nature of complexes.
CONCLUSIONS:
The concentration distribution of various species formed in solution was evaluated. The Cu(II) complexes have been synthesized and the coordination sites of the ligands were characterized by means of IR spectroscopy.
