MSG3000: Mass Spect Gold Human Serum, Ultra-Low Hormones & Steroids, Lipid Free

A recent study presents a validated method for measuring 22 fatty acids (C12–C22) in plasma and serum using GC-NCI-MS. The method uses pentafluorobenzyl (PFB) esters to enhance sensitivity and measures fatty acids with high precision (R² ≥ 0.990, CV ≤ 13.2%). Samples remained stable for 75+ days at -20°C and through multiple freeze-thaw cycles.

Mass Spect Gold™ Human Serum (MSG3000) was used as a lipid-free matrix to establish a consistent baseline for the analysis. For a detailed look at the study's findings and the specific use of MSG3000 serum, you can read the full article at ScienceDirect.

The study evaluated the stability of cut estradiol patches from four brands used off-label for pubertal induction in hypogonadal girls. Patches were cut into smaller pieces and stored for one month at 21°C and 35°C. Systen, Estraderm MX, and Oesclim maintained stable estradiol levels at both temperatures, while cut Estradot patches lost 57% of their estradiol at 35°C.

MSG3000 was employed as the reconstitution matrix for estradiol extraction, ensuring assay conditions closely mimic human serum for accurate radioimmunoassay quantification. These findings support using cut patches from Systen, Estraderm MX, and Oesclim for pubertal induction when stored appropriately, whereas Estradot is not recommended due to its instability at elevated temperatures.

This study presents the development and validation of a sensitive liquid chromatography-tandem mass spectrometry (LC–MS/MS) method to directly quantify steroidal glucuronide conjugates in postmenopausal women’s serum. This method offers better specificity, sensitivity, and speed (less than 6 min run time) than traditional assays and aligns with FDA guidelines.

In this study, MSG3000 from Golden West Diagnostics, a stripped human serum, was used to prepare the serum matrix for method validation, ensuring that the assay could accurately measure the glucuronides. The developed method demonstrated full compliance with bioanalytical guidelines and was suitable for large-scale clinical analyses.

The study aimed to improve the measurement of aldosterone; a hormone essential for diagnosing primary hyperaldosteronism. The authors developed a sensitive and fast 2D-LC–MS/MS method that requires a low sample volume and achieves higher specificity than commercial immunoassays, which were found to overestimate aldosterone levels.

This method's linearity indicates its suitability for analyzing urine and adrenal venous samples. The paper demonstrates the 2D-LC–MS/MS method's potential for enhanced clinical diagnostics due to its high specificity and cost-effective operation.

The assay's limit of quantitation (LOQ) was established using MSG3000, an aldosterone-depleted serum from Golden West Diagnostics, ensuring accuracy in aldosterone detection.

This study compares four LC-MS/MS assays for measuring testosterone levels. The focus was on evaluating the analytical specificity of the assays by measuring testosterone in women's serum, free of the influence of exogenous testosterone.

The study utilizes Golden West Diagnostic’s human serum (MSG3000) as a testing matrix to eliminate possible testosterone contamination.
