ENZO熱銷產(chǎn)品——LTB4 ELISA kit，白三烯B4檢測試劑盒

白三烯（Leukotriene, LT）是花生四烯酸的5-脂氧合酶代謝的主要產(chǎn)物，能夠刺激白細(xì)胞的功能，包括溶酶體酶的釋放、粘附和多形核白細(xì)胞（即嗜中性、嗜堿性和嗜酸性白細(xì)胞）的聚集，被認(rèn)為是炎癥性疾病和免疫調(diào)節(jié)的強(qiáng)效介質(zhì)。半胱氨酰白三烯（LTC4、LTD4和LTE4）是通過將半胱氨酸衍生物加到LTA4上形成的，LTC4合酶將LTA4轉(zhuǎn)化為LTC4限制了半胱氨酰白三烯的形成速率。半胱氨酰白三烯作為炎癥中的強(qiáng)效脂質(zhì)介質(zhì)，可誘導(dǎo)平滑肌收縮和毛細(xì)血管通透性增加。

Enzo Life Sciences的高品質(zhì)熱銷產(chǎn)品LTB4 ELISA kit（貨號：ADI-900-068）具有超高靈敏度和高文獻(xiàn)引用率，批次間差異小，上市多年廣受用戶好評。

高分文獻(xiàn)引用：

近期，Adams發(fā)表了題為《Leukotriene A4 hydrolase inhibition improves age-related cognitive decline via modulation of synaptic function》的文章，在該項(xiàng)研究中，Adams等人使用了Enzo的LTB4 ELISA試劑盒檢測小鼠血漿，測定了老年小鼠、給藥白三烯A4水解酶抑制劑（LTA4H）的小鼠體內(nèi)炎癥介質(zhì)白三烯B4（LTB4）水平，證明了LTA4H抑制劑可以減少LTB4的產(chǎn)生，并改善小鼠與年齡相關(guān)的認(rèn)知能力下降。

(A) Plasma LTB4 measured from unstimulated blood is significantly increased from 3 to 22.5 months (M). Unpaired t test, **P = 0.0011, F = 2.952 (n = 15 and 11). (B) Plasma LTB4 levels from calcimycin-stimulated blood are significantly reduced following 4 weeks of dosing with LTA4H inhibitors AKST1220 or SC57461A. Kruskal-Wallis test, P = 0.0006 followed by Dunn’s multiple comparisons: vehicle versus AKST1220, **P = 0.0034; vehicle versus SC57461A, *P = 0.0212; and AKST1220 versus SC57461A, P > 0.9999 (n = 5, 6, and 9).

Adams團(tuán)隊對LTB4 ELISA kit的真實(shí)評價：

Q: Why did you use Enzo’s LTB4 ELISA Kit?

A: Species-independent measurement of LTB4 in culture supernatant, plasma, saliva, urine, and other cited sample types.

Q: How do you position Enzo’s LTB4 ELISA Kit?

A: The LTB4 ELISA kit is a colorimetric competitive enzyme immunoassay kit with results in 4 hours. It is designed to assay up to 39 samples in duplicate with a broad dynamic range that is suitable for a wide variety of sample matrices, including bronchioalveolar lavage fluid, cell lysate, crevicular fluid, tissue, serum and whole blood.
