【Calcein AM Fluorescent Dye】活細胞染劑 Calcein AM 如何配製。TREVIGEN、BIOVISIO 萊恩生物科技有限公司代理 04-25239639。





活細胞螢光染劑 Calcein AM,用於活細胞觀察及細胞侵入定量實驗, 1755-250

Catalog#: 1755-250 | Size: 5 x 50 µg
活細胞染劑 “Calcein AM”, 用於活細胞觀察及細胞侵入及轉移試劑.
配製方法:
50ugcalcein AM可以溶在50ulDMSO 最後濃度為1Mm
1ulCalcein AM 溶在1X 1000ul dissociation solution =1uM (1000ul)96well 為例, 加入100ul1Um Calcein AM,大約可以使用500.
Calcein acetoxymethylester (Calcein AM) is a non-fluorescent, cell permeate compound that is hydrolyzed by intracellular esterases into the fluorescent anion calcein.


Calcein-AM是一種可對活細胞進行螢光標記的細胞染色試劑,Calcein-AM由於在Calcein(鈣黃綠素)的基礎上加強了疏水性,因此能夠輕易穿透活細胞膜。當其進入到細胞質後,酯酶會將其水解為Calcein(鈣黃綠素)留在細胞內,發出強綠色螢光。
與其他同類試劑(如BCECF-AMCarboxy-fluorescein diacetate)相比,Calcein-AM是最適合作為螢光探針去染活細胞的,因為它的細胞毒性很低。Calcein(鈣黃綠素)不會抑制任何的細胞功能如增殖或淋巴球的趨化性。另外,使用了Calcein(鈣黃綠素)的活性檢測的實驗結果是十分可信並且與標準的51Cr-釋放法所得結果相一致的。
Calcein(鈣黃綠素)的激發和發射波長分別為490 nm515 nmCalcein-AM和碘化丙啶(PI)溶液,它們分別可對活細胞和死細胞染色。Calcein-AM的乙酸甲基酯親脂性很高,使其可透過細胞膜,通過活細胞內的酯酶作用,Calcein-AM能脫去AM基,產生的Calcein(鈣黃綠素)能發出強綠色螢光,因此Calcein-AM僅對活細胞染色。另一方面,作為核染色染料的PI不能穿過活細胞的細胞膜。它穿過死細胞膜的無序區域而到達細胞核,並嵌入細胞的DNA雙螺旋從而產生紅色螢光(激發:535 nm,發射:617 nm),因此PI僅對死細胞染色。由於Calcein(鈣黃綠素)PI-DNA都可被490 nm激發,因此可用螢光顯微鏡同時觀察活細胞和死細胞。用545 nm激發,僅可觀察到死細胞。根據以上特點,Calcein-AM和碘化丙啶(PI)經常被結合用來作為活細胞和死細胞的雙重染色。


BIOVISION and TREVIGEN™ Calcein AM Fluorescent Dye can be used to fluorescently label viable cells for a variety of assays such as tumor cell invasion, endothelial cell migration, and endothelial cell tubulogenesis.

Description: A cell-permeable, non-fluorescent acetoxymethyl ester derivative of Calcein that gets hydrolyzed inside the cell by esterases. The loss of the acetoxymethyl group also enables calcein to readily bind intracellular calcium resulting in a strong yellowish-green fluorescence. It is the best probe for cell viablilty and cell adhesion due to its greater retention in cells as well and its pH insensitivity in physiological range.
Handling: Protect from air and light
USAGE: For Research Use Only! Not For Use in Humans.

.
The Quick Cell Proliferation Assay Kit provides all reagents and detailed instructions for a fast and sensitive quantification of cell proliferation and viability. The assay is based on the cleavage of the tetrazolium salt WST-1 to formazan by cellular mitochondrial dehydrogenases. Expansion in the number of viable cells resulted in an increase in the activity of the mitochondrial dehydrogenases, which leads to the increase in the amount of formazan dye formed. The formazan dye produced by viable cells can be quantified by multi-well spectrophotometer (microtiter plate reader) by measuring the absorbance of the dye solution at 440 nm. The assay can be used for the measurement of cell proliferation in response to growth factors, cytokines, mitogens, and nutrients, etc. It can also be used for the analysis of cytotoxic compounds like anticancer drugs and many other toxic agents and pharmaceutical compounds. The new method is so simple, requiring no washing, no harvesting, and no solubilization steps, and is faster and more sensitive than MTT, XTT, or MTSbased assays. The entire assay can be performed in a microtiter plate.

BIOVISION粒線體染劑JC-1 (Catalog#1130-5),測量粒線體膜電位改變【萊恩生物科技有限公司04-25239639】BIOVISION代理

JC-1 ( 5, 5’ ,6, 6’ -tetrachloro-1, 1’ ,3, 3’ -tetraethyl-benzimidazolylcarbocyanine Iodide_Catalog#: 1130-5 | Size: 5 mg

JC-1 染劑是一種粒線體染劑(mitochondrial dye)。JC-1染劑可以測量粒線體膜電位,染出粒線體膜電位失衡現象。其原理為: 當帶正電的JC-1染劑進入細胞中,會被粒線體膜上的負性電場所吸引並聚集形成二聚體,在螢光顯微鏡下發出橘組色螢光;若是粒線體上膜電位消失,使JC-1染劑無法被膜上電場所吸引,而散佈在細胞中,並呈現單體狀態,在螢光顯微鏡下發出綠色螢光。JC-1染劑可以用來觀察細胞凋亡現象,在健康的細胞中,發出紅色螢光;當細胞胞凋亡發生時,發出綠色染光。
Description: JC-1 is a mitochondrial dye that stains mitochondria in living cells in a membrane potential-dependent fashion. JC-1 monomer is in equilibrium with so called J-aggregates, which are favored at higher mitochondrial membrane potential. The monomer JC-1 has green fluorescence (lem = 527 nm), while the J-aggregates have red fluorescence (lem = 590 nm). Therefore, it has been possible to use fluorescence ratioing technique to study mitochondrial membrane potential. JC-1 is particularly useful for apoptosis studies. In apoptotic cells, the dye stays in the cytoplasm and fluoresces green, while in healthy cells, the dye aggregates in the mitochondria and fluoresces red.

    • The assay can be done directly in culture plates requiring no harvest/washing/or sample preparations. The assay can be fully automatic for high throughput (10 seconds/sample) and is highly sensitive (detects 10-100 mammalian cells/well).
    Kit components:
    • Nucleotide Releasing Buffer
    • ATP Monitoring Enzyme
    • Enzyme Reconstitution Buffer
    • ATP (MW 551)
    Description:
    Cell death (especially apoptosis) is an energy-dependent process that requires ATP. As ATP levels fall to a point where the cell can no longer perform basic metabolic functions, the cell will die. A typical apoptotic cell exhibits a significant decrease in ATP level. Therefore, loss of ATP level in cell has been used as an indicator of cell death. In contrast, cell proliferation has been recognized by increased levels of ATP. The ApoSENSOR™ Cell Viability Assay Kit utilizes bioluminescent detection of the ATP levels for a rapid screening of apoptosis and cell proliferation simultaneously in mammalian cells. The assay utilizes luciferase to catalyze the formation of light from ATP and luciferin, and the light can be measured using a luminometer or Beta Counter. The assay can be fully automatic for high throughput (10 seconds/sample) and is extremely sensitive (detects 10-100 mammalian cells/well). The high sensitivity of this assay has led to many other applications for detecting ATP production in various enzymatic reactions, as well as for detecting low level bacterial contamination in samples such as blood, milk, urine, soil, and sludge.
