Low dose estrogen pellets

Manufactured by Innovative Research
Visit Supplier

Low-dose estrogen pellets are a form of hormone replacement therapy. They contain a controlled amount of estrogen, which is a female sex hormone. The pellets are designed to be implanted subcutaneously and release the estrogen gradually over an extended period.

Bone-derived MCF-7-5624A cells were maintained in DMEM supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin7 (link). The authenticity of the animal-derived line to the parental line was tested using the cell line authentication services using Short Tandem Repeat (STR) profiling (ATCC, VA). MCF-7-5624A tumor cells were injected into the left cardiac ventricle (5 × 105 cells) in 3–4 week old homozygous female athymic nude mice (Taconic, Hudson, NY) supplemented with low-dose estrogen pellets (0.18 mg; Innovative Research of America, Sarasota, FL) that deliver 2 μg/day of 17β estradiol. Tumor progression and size was monitored through BLI and MRI. Mice received weekly injections of ReANCs or fReANCs functionalized with 12.5 μM AMD3100 at 10 mg/kg body weight and were imaged immediately post injection and up to 24 hours post administration. SWIR signal from the leg bones and the dorsal area corresponding to the location of the adrenal glands was quantified. Animals were sacrificed upon weight loss and organs were excised. Tumor volume was calculated using 3D reconstructions generated from MRI imaging.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
