一般描述
用于质量控制的制药二级标准品，为制药实验室和制造商制备内部工作标准品提供了一种方便、高性价比的替代方案。2-丁酮（甲基乙基酮，MEK）是一种脂肪族酮，被认为是一种非质子和亲质子溶剂。研究报道了它在锂-毛果芸香碱诱导的大鼠癫痫持续状态中作为抗惊厥剂的能力。
应用
这些二级标准品是合格的认证标准物质（CRM）。它们适用于多种分析应用，包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他校准需求。
分析说明
These secondary standards offer multi-traceability to the US and EP primary standards, where they are available.

CXCR4(WHIM) frameshift and nonsense mutations follow MYD88(L265P) as the most common somatic variants in Waldenström Macroglobulinaemia (WM), and impact clinical presentation and ibrutinib response. While the nonsense (CXCR4(S338X) ) mutation has been investigated, little is known about CXCR4 frameshift (CXCR4(FS)

T helper (TH) cell polarization during priming is modulated by a number of signals, but whether polarization to a given phenotype also influences recall responses of memory TH cells is relatively unknown. Here we show that miR-181a is selectively induced

Basal and kinase inhibitor driven adaptive signaling has been examined in a panel of melanoma cell lines using phosphoproteomics in conjunction with pathway analysis. A considerable divergence in the spectrum of tyrosine-phosphorylated peptides was noted at the cell line level.

The constitutive androstane receptor (CAR) is a crucial transcriptional regulator of key xenobiotic-metabolizing enzymes such as cytochrome P450 CYP3A4, CYP2C9 and CYP2B6. The flavonoids chrysin, baicalein and galangin have been reported to activate CAR and interfere with EGFR signaling. Nevertheless
