To investigate the biological importance of 24Rhydroxylation of 25-hydroxyvitamin D to the early development of rats, the potency of 24,24-difluoro-25-hydroxyvitamin D 3 had been compared to that of 25-hydroxyvitamin D 3 in young rat pups born to vitamin D-deficient mothers. 24,24-Difluoro-25-hydroxyvitamin D 3 and 25-hydroxyvitamin D 3 were equally active in stimulating active calcium ...
1,5-Difluoro-2,Cdinitrobenzene (mol wt, 204) was purchased from K and K Laboratories, Inc. To prevent hydrolysis the re- agent was stored at 5" in a tightly closed bottle over anhydrous calcium chloride. 2,4-Dinitrophenylene-l, 5-RNase was prepared by the reac-
Four side chain fluorinated analogues of 1α,25-dihydroxy-19-norvitamin D have been prepared in convergent syntheses using the Wittig–Horner reaction as a key step. Structures and absolute configurations of analogues 3 and 5 were confirmed by X-ray crystallography. All analogues showed high potency in HL-60 cell differentiation and vitamin D-24-hydroxylase (24-OHase) transcription as ...
New derivative of vitamin D, 23,23-difluoro-25-hydroxycholecalciferol, a method for preparing said compound and various new intermediates utilized in such process.The compound is characterized by vitamin D-like activity as evidenced by its ability to increase intestinal calcium transport and serum calcium.It is further characterized by its resistance to hydroxylation at C-23, which is ...
A fluorescent labeling reagent for the detection of intracellular calcium. Binds to intracellular calcium (K d = 345 nM). Fluo-4 is an analog of Fluo-3 with the two chlorine substituents replaced by fluorines, which results in increased fluorescence excitation at 488 nm and .
Another option is to use HTH granular calcium hypochlorite (pool shock with around 60-70% free chlorine) instead of bleach (changes the recipe) as the source of free chlorine or use it to make bleach stock. If kept in a desiccator, it has a long shelf life and is very inexpensive. Either way, you can test for the amount of free chlorine using ...
Fluo-4 AM is an improved analog of the popular calcium indicator Fluo-3 AM. Fluo-4 AM loads faster and is brighter at equivalent concentrations, making it the preferred indicator for confocal microscopy, flow cytometry and microplate screening applications. Application
