Introduction | Interleukin-1 alpha is a proinflammatory cytokine produced by a wide variety of cell types, including macrophages, osteoblasts, monocytes and hepatocytes. Circulating levels of are normally low and only rise after stimulation by agents such as those produced byinflammation, infection or microbial endotoxins. IL-1 alpha possesses a wide variety of biological activities and exerts its effects by binding to specific cell surface receptors. | |||||
Description | Interleukin-1A Rat Recombinant produced in E.Coli is single, a non-glycosylated, Polypeptide chain containing 155 amino acids and having a molecular mass of 17703 Dalton. The IL-1A is purified by proprietary chromatographic techniques. | |||||

適用范圍:此試劑盒僅用于科研實(shí)驗(yàn),禁用于臨床
人缺氧誘導(dǎo)因子-1α(HIF-1α)elisa試劑盒等ELISA試劑盒操作技術(shù)相關(guān)的注意事項(xiàng):
⑴ 嚴(yán)格按照人缺氧誘導(dǎo)因子-1α(HIF-1α)elisa試劑盒說明書進(jìn)行操作。操作前將試劑在室溫下平衡30~60min。
⑵ 加樣后及時放人孵箱。標(biāo)本較多時,要分批操作。按說明步驟嚴(yán)格控制操作時間,防止孵育時間人為延長,導(dǎo)致非特異性結(jié)合緊附于反應(yīng)孔周圍,難以清洗徹底。
(3)封板溫育時,各孔一定要封嚴(yán),防止陽性標(biāo)本的液體蒸發(fā),產(chǎn)生周邊現(xiàn)象從而導(dǎo)致“花板”的出現(xiàn)。
(4)用洗板機(jī)洗板時,保證洗液注滿各孔,洗板針暢通,洗完板后最好在吸水紙(選擇干凈、無或少塵的吸水材料)上輕輕拍干:還要防止針口有纖維蛋白或異物,這些異物在洗板的過程中易產(chǎn)生拖帶現(xiàn)象而導(dǎo)致“花板”的出現(xiàn)。
(5)合理安排檢測量,以免反應(yīng)板過多造成洗板等待時間長。
(6)加酶試劑后用吸水紙?jiān)诿笜?biāo)板表面輕拭吸干。
(7)顯色劑盡量在臨用前配制,堅(jiān)持不用過期顯色劑,肉眼可見淺藍(lán)色的TMB顯色劑不用。
(8)加樣時保持顯色劑不外流;A、B液應(yīng)避免接觸金屬器械。加終止液時應(yīng)避免產(chǎn)生氣泡。
(9)應(yīng)保證C清潔,整個操作過程中保證酶標(biāo)板不接觸次氯酸。以上的措施可以使“花板”降至最低限度。從而提高檢測的特異性。并得到更準(zhǔn)確、可靠的實(shí)驗(yàn)結(jié)果。
人缺氧誘導(dǎo)因子-1α(HIF-1α)elisa試劑盒實(shí)驗(yàn)數(shù)據(jù)處理方法:
如果是新的數(shù)據(jù),你只要雙擊圖表,把它輸入到圖表的數(shù)據(jù)中,就可以擬和曲線。根據(jù)曲線方程式,計(jì)算出濃度。
方法:
1、擬和曲線:
輸入第一行: 濃度值, 如0 10 50 100 400
輸入第二行:該濃度下的調(diào)整后的od值,如0 0.586 1.397 1.997 3.42
選擇這些輸入的數(shù)據(jù),用插入里的圖表按鈕,進(jìn)入圖表向?qū),?ldquo;標(biāo)準(zhǔn)類型”中選擇“xy散點(diǎn)圖”;在“子圖表類型”中選擇“折線散點(diǎn)圖”,按“下一步”;選擇“系列產(chǎn)生在行”,按“下一步”;數(shù)據(jù)標(biāo)志,可以填寫:如數(shù)據(jù)y軸,OD值;數(shù)據(jù)x軸,濃度;按下一步,點(diǎn)擊完成?傻们圖。
單擊曲線,按右鍵,選擇“添加趨勢線”,在類型中,選擇多項(xiàng)式;在選項(xiàng)中,選擇顯示公式,選擇顯示R平方值。
得到公式和R平方值。
也可以用上面說的方法: 雙擊圖表,把它輸入到圖表的數(shù)據(jù)中,就可以擬和曲線。
2、計(jì)算濃度:
第一次實(shí)驗(yàn):
標(biāo)準(zhǔn)曲線為:
y = -4E-05x2 + 0.026x
R2 = 0.9745
為例,已知OD值,計(jì)算濃度。
由于y = -4E-05x2 + 0.026x,所以可以得到:
4E-05x2 -0.026x +y=0
ax2 +bx +y=0
a=4E-05;b= -0.026;
x=(-b-(b*b-4ay)(平方根)) /(2*a)
代入a,b,和y值,得
x=(0.026-(0.026*0.026-0.00016*y)(平方根))/(2*0.00004)
在excel里可以用以下公式表示:
x=(0.026-EXP(LN(0.026*0.026-0.00016*y)/2))/(2*0.00004)
人缺氧誘導(dǎo)因子-1α(HIF-1α)elisa試劑盒數(shù)據(jù)計(jì)算通用公式為:
x=(-b-EXP(LN(b*b-4ay)/2))/(2*a)
您可以應(yīng)用excel的公式拷貝功能,計(jì)算所有濃度

輻射儀/αβγX射線型號:RD1212
相關(guān)產(chǎn)品名稱:Radalert100 α、β、γ和χ多功能表面污染儀
應(yīng)用領(lǐng)域:1、監(jiān)測個人輻射暴露2、地區(qū)或周界監(jiān)測3、監(jiān)測輻射泄漏和污染4、確保符合管理部門規(guī)定5、監(jiān)測本底輻射的變化6、核物理原理演示7、檢查輻射性礦物
儀器的工作原理:
每次射線穿過蓋革管并引起電離時,蓋革計(jì)數(shù)管會產(chǎn)生一脈沖電流。每個脈沖都是電子探測并進(jìn)行運(yùn)算。探測器以你選擇的模式顯示計(jì)算:CPM,mR/hr,或者總計(jì)。在s1單位中,使用CPS和μsv/hr。檢測器探測出來的計(jì)數(shù)數(shù)字由于放射能的任意狀態(tài)而每分鐘都在變化。以過去一段時間內(nèi)的平均值表示更加,而且這段時間越長數(shù)據(jù)越。
