產(chǎn)品名稱:瑞氏染液售后服務(wù)
英文名字:Wright's stain solution
產(chǎn)品描述
瑞氏染料是由堿性染料美藍(lán)(Methvlem blue)和酸性染料伊紅(Eostm Y)組成的復(fù)合染料,溶于甲醇 。伊紅通常為鈉鹽,有色部分為陰離子。美藍(lán)通常為氯鹽,有色部分為陽離子。甲醇的作用:一是溶解美藍(lán)和伊紅,使其解離為有色美藍(lán)正離子的和伊紅負(fù)離子。后兩者可以選擇性地吸附于血細(xì)胞內(nèi)的不同成分而使其著色;二是固定細(xì)胞形態(tài),加速染色反應(yīng),增強(qiáng)染色效果。
產(chǎn)品優(yōu)勢(shì)
染色方法簡單、快速,效果穩(wěn)定。
儲(chǔ)存條件
室溫避光保存,有效期至少2年。
瑞氏染液售后服務(wù)注意事項(xiàng)
1、 涂片厚薄適宜,涂片干透后固定,否則細(xì)胞在染色過程中容易脫落。
2、 所加染液不能過少,以免蒸發(fā)而使染料沉淀。沖洗時(shí)間不能過久,以防脫色。
3、 染色對(duì)pH十分敏感,稀釋染液必須用緩沖液,沖洗用水應(yīng)接近中性,否則可能會(huì)導(dǎo)致細(xì)胞染色異常,形態(tài)難以識(shí)別,甚至錯(cuò)誤。
4、 染色過淡可以復(fù)染,復(fù)染時(shí)應(yīng)先加緩沖液,然后加染液。染色過深可用流水沖洗或浸泡,也可用甲醇脫色。
瑞氏染液售后服務(wù)產(chǎn)品應(yīng)用:
對(duì)于一些相對(duì)特殊的產(chǎn)品,我們會(huì)提供產(chǎn)品說明書,里面會(huì)對(duì)產(chǎn)品溶解性,及我們所能了解的產(chǎn)品應(yīng)用信息,實(shí)驗(yàn)方案進(jìn)行描述,您可以作為參考。對(duì)于常見試劑,因?yàn)閼?yīng)用廣泛,一般不提供說明書。如果您在實(shí)驗(yàn)過程中遇到了問題,歡迎與我們討論,我們將盡力幫您解決。
瑞氏染液售后服務(wù)分裝及溶液配制:
您收到貨物后不要自己進(jìn)行分包,因?yàn)榉职h(huán)境、包裝材料等因素可能導(dǎo)致分包后的產(chǎn)品變質(zhì);如您有特殊包裝要求,請(qǐng)?jiān)谟嗁彆r(shí)候與我們客服代表闡明,當(dāng)然價(jià)格會(huì)做適當(dāng)調(diào)整。對(duì)于開蓋后,長期未使用的,請(qǐng)務(wù)必重新密封好,建議Parafilm封口膜,并按照相應(yīng)儲(chǔ)存條件使用。如果放置時(shí)間過長,超過產(chǎn)品有效期,建議您重新購買,以免影響實(shí)驗(yàn)質(zhì)量。
瑞氏染液售后服務(wù)儲(chǔ)存條件:
大部分的試劑產(chǎn)品是比較穩(wěn)定的,只要您嚴(yán)格按照產(chǎn)品包裝或者說明書上的儲(chǔ)存條件進(jìn)行儲(chǔ)存,*可以保證其在有效期內(nèi)的正常使用。一般常見儲(chǔ)存條件有零下XX攝氏度,2-8攝氏度,常溫等。特別提醒,對(duì)于某些酶類制品,如果儲(chǔ)存條件是2-8攝氏度,不要儲(chǔ)存在零下,否則容易失活,對(duì)于某些需要嚴(yán)格避光,防潮,充氮?dú)獗Wo(hù)的,接觸空氣或者過分暴露非常容易氧化或者受潮變質(zhì)。
低溫儲(chǔ)存產(chǎn)品,運(yùn)輸途中冷藏問題:
對(duì)于需要低溫儲(chǔ)存的產(chǎn)品,我們?cè)谶\(yùn)輸時(shí)候都會(huì)采用冷藏包裝,但是部分由于外界氣溫過高,運(yùn)輸時(shí)間較長,對(duì)于普通冷藏包裝,途中可能會(huì)溫度升高,這些都是沒有問題的,因?yàn)檫@種普通冷藏只適用于那些短期內(nèi)(2周)高溫依然穩(wěn)定的產(chǎn)品,建議低溫的儲(chǔ)存條件,只是長期儲(chǔ)存時(shí)候的條件,您可以放心使用。對(duì)于某些特殊的產(chǎn)品,如抗體,我們會(huì)采用干冰冷藏包裝,確保全程低溫。公司都對(duì)產(chǎn)品性狀進(jìn)行了嚴(yán)格的加速穩(wěn)定測(cè)試,行業(yè)經(jīng)驗(yàn)豐富。
瑞氏染液售后服務(wù)儲(chǔ)存條件:避光、干燥陰涼處封閉貯存,嚴(yán)禁與有毒、有害物品混放、混運(yùn)。本品為非危險(xiǎn) 產(chǎn)品可按一般化學(xué)品運(yùn)輸,輕搬動(dòng)輕放,防止日曬、雨淋!受熱、受潮、受光后易喪失活力,保存期短,因此貯存和運(yùn)輸條件比較苛刻。
5'CAGGTG-3'. Capable of reversing CTBP1-mediated transcription repression. Component of a splicing-dependent multiprotein exon junction complex (EJC) deposited at splice junction on mRNAs. The EJC is a dynamic structure consisting of a few core proteins and several more peripheral nuclear and cytoplasmic associated factors that join the complex only transiently either during EJC assembly or during subsequent mRNA metabolism. Participates in the regulation of alternative pre-mRNA splicing. Associates to spliced mRNA within 60 nt upstream of the 5'-splice sites. Involved in the establishment and maintenance of epithelia cell-cell adhesion. Potential tumor suppressor for renal cell carcinoma.
