Oxford牛津X-MET5000(手持式XRF元素分析仪)

牛津仪器推出了新款手持式X射线荧光光谱仪， 可满足各种苛刻的元素分析要求。

牛津仪器宣布推出一款坚固的手持式X射线荧光光谱仪(XRF) — X-MET5000，该仪器能够进行高精度、高可靠性的元素分析。牛津仪器的手持式X射线荧光光谱仪誉满全球，X-MET5000是其第四代产品。

这款全新的光谱仪拥有高性能和高可靠性，它综合了牛津仪器的PentaFET专利探测器技术，能够保证所有用户感兴趣的元素均得到快速分析，并且提供更低的元素检测下限。 这款光谱仪专门为各种最严格的质量控制应用而设计，例如金属废料回收利用、合金分类鉴定以及玩具和消费产品的含铅量检测结果是否符合RoHS指令要求。此外，X-MET5000还能满足采矿业的需求，也可在环境监测行业中用于测定土壤中的重金属含量。

X-MET5000的主要优势就在于其轻元素处理 (LET) 模式，此模式可允许对重金属进行快速、准确的分析——即使样品中存在铝和硅等轻元素，仍不会影响其分析结果。而其他普通分析仪由于只使用“基本参数（FP）法”，根本无法分析由于轻元素的存在对最终的分析结果造成的干扰。

这款坚固、可靠的工具通过了IP54 (NEMA 3)认证，具备卓越的防水防尘性能。X-MET5000是恶劣应用环境的理想选择。该仪器所配备的电池可持续使用一个工作日，从而提高了工作效率。

其强大的用户自定义软件能够提供准确的分析结果，从而提高了“合格/不合格”决定的可靠性。X-MET5000能够识别材料类型，并自动选择最佳分析方法。

借助于其可选配的台式支架，可免除执行多分析任务时的手工操作，同时又不会令测量结果的置信水平受到任何影响。

生物活性

N-Formyl-Met-Leu-Phe (fMLP; N-Formyl-MLF) is a chemotactic peptide and a specific ligand of N-formyl peptide receptor (FPR). N-Formyl-Met-Leu-Ph is reported to inhibit TNF-alpha secretion.

IC50 Target

TNF-alpha[1]
体外研究
(In Vitro)

Binding of N-Formyl-Met-Leu-Phe to its specific cell surface receptor, N-formyl peptide receptor (FPR), triggers different cascades of biochemical events, eventually leading to cellular activation. FPR is a chemoattractant receptor belonging to the G protein-coupled receptor family. N-Formyl-Met-Leu-Phe promotes osteoblastic commitment and suppresses adipogenic commitment under osteoblastic differentiation conditions. N-Formyl-Met-Leu-Phe stimulates osteogenesis is associated with increased expression of osteogenic markers and mineralization. N-Formyl-Met-Leu-Phe inhibits expression of peroxisome proliferator-activated receptor-γ1. N-Formyl-Met-Leu-Phe-stimulated osteogenic differentiation is mediated via FPR1-phospholipase C/phospholipase D-Ca2+-calmodulin-dependent kinase II-ERK-CREB signaling pathways[1]. N-Formyl-Met-Leu-Phe, a bacterial-derived peptide, induced proinflammatory cytokine gene expression in human peripheral blood monocytes. Bacterial products LPS and N-Formyl-Met-Leu-Phe synergistically induce inflammatory response via multiple signaling pathways. TLR4, IKKβ-IκBα, and NF-κB signaling pathways are involved in the synergistic induction of TNF-α via p65 nuclear translocation-dependent mechanisms[2].

体内研究
(In Vivo)

N-Formyl-Met-Leu-Phe promotes bone formation in zebrafish and rabbits. Extensive skeletal development is evident at 5 dpf in over 80% of N-Formyl-Met-Leu-Phe-treated zebrafish. Treatment with N-Formyl-Met-Leu-Phe results in increased expression of Runx2. Bone marrow spaces are widely formed, and connective tissue covering bone is dense, like periosteum, in N-Formyl-Met-Leu-Phe-treated calvaria[1]. N-Formyl-Met-Leu-Phe mediate release of calprotectin from PMN in vitro. It induces release of calprotectin from PMN in a dose dependent manner. A minimum of 10% of total PMN calprotectin is retained at concentrations of 0.1-10.0 nM of N-Formyl-Met-Leu-Phe[3].

Cell Assay
[2]

Cells are cotransfected with either a dominant negative form of IκBα or a dominant negative form of IKKβ together with the NF-κB-dependent luciferase reporter plasmid. The plasmid pCMVβ is used as a control for transfection efficiency and this is monitored via the expression of β-galactosidase. Cells are transiently transfected with plasmids using DEAE-dextran. The transfected cells are cultivated for 48 h before a 6-h incubation in medium ±N-Formyl-Met-Leu-Phe, LPS, or N-Formyl-Met-Leu-Phe/LPS. Luciferase activity is determined by using the luciferase assay kit and a Monolight 3010 luminometer[2].

Animal Administration
[2]

Mice: N-Formyl-Met-Leu-Phe is prepared in sterile PBS. Under the anesthesia, mice are intranasally treated with LPS (0.3 mg/kg) or N-Formyl-Met-Leu-Phe (0.5 mg/kg) or N-Formyl-Met-Leu-Phe and LPS in 50 μL of sterile PBS (control), BAL is performed by cannulating the trachea with sterilized PBS, and cells from BAL fluid are stained with Wright-Giemsa stain after cytocentrifuge. For TNF-α protein release, BAL fluid is collected and secreted TNF-α is measured by ELISA as described above[2].

Tyr-Gly-Gly-Phe-Met-OH regulates human immune function and inhibits tumor growth via binding to the opioid receptor.

IC50 Target

Opioid Receptor[1].
体外研究
(In Vitro)

Methionine enkephalin (MENK), an endogenous neuropeptide has a crucial role in both neuroendocrine and immune systems. MENK is believed to have an immunoregulatory activity to have cancer biotherapy activity by binding to the opioid receptors on immune and cancer cells. MENK may also change the tumor microenvironment by binding to opioid receptor on or in cancer cells. All of these mechanisms of action have biologic significance and potential for use in cancer immunotherapy. Furthermore, they reveal a relationship between the endocrine and immune systems[1].

生物活性

[Sar9,Met(O2)11]-Substance P TFA is a tachykinin NK1 receptor selective agonist.

IC50 Target

NK1 receptor[1]
体外研究
(In Vitro)

[Sar9,Met(O2)11]-Substance P and septide (10-100 pmol per rat, i.c.v.) are equipotent in increasing mean arterial blood pressure (MAP) and heart rate (HR), yet they have dissimilar time-course. Both agonists increase dose-dependently face washing and sniffing while [Sar9,Met(O2)11]-Substance P is the sole to produce grooming[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
