产品名称:瑞氏染液售后服务
英文名字:Wright's stain solution
产品描述
瑞氏染料是由碱性染料美蓝(Methvlem blue)和酸性染料伊红(Eostm Y)组成的复合染料,溶于甲醇 。伊红通常为钠盐,有色部分为阴离子。美蓝通常为氯盐,有色部分为阳离子。甲醇的作用:一是溶解美蓝和伊红,使其解离为有色美蓝正离子的和伊红负离子。后两者可以选择性地吸附于血细胞内的不同成分而使其着色;二是固定细胞形态,加速染色反应,增强染色效果。
产品优势
染色方法简单、快速,效果稳定。
储存条件
室温避光保存,有效期至少2年。
瑞氏染液售后服务注意事项
1、 涂片厚薄适宜,涂片干透后固定,否则细胞在染色过程中容易脱落。
2、 所加染液不能过少,以免蒸发而使染料沉淀。冲洗时间不能过久,以防脱色。
3、 染色对pH十分敏感,稀释染液必须用缓冲液,冲洗用水应接近中性,否则可能会导致细胞染色异常,形态难以识别,甚至错误。
4、 染色过淡可以复染,复染时应先加缓冲液,然后加染液。染色过深可用流水冲洗或浸泡,也可用甲醇脱色。
瑞氏染液售后服务产品应用:
对于一些相对特殊的产品,我们会提供产品说明书,里面会对产品溶解性,及我们所能了解的产品应用信息,实验方案进行描述,您可以作为参考。对于常见试剂,因为应用广泛,一般不提供说明书。如果您在实验过程中遇到了问题,欢迎与我们讨论,我们将尽力帮您解决。
瑞氏染液售后服务分装及溶液配制:
您收到货物后不要自己进行分包,因为分包环境、包装材料等因素可能导致分包后的产品变质;如您有特殊包装要求,请在订购时候与我们客服代表阐明,当然价格会做适当调整。对于开盖后,长期未使用的,请务必重新密封好,建议Parafilm封口膜,并按照相应储存条件使用。如果放置时间过长,超过产品有效期,建议您重新购买,以免影响实验质量。
瑞氏染液售后服务储存条件:
大部分的试剂产品是比较稳定的,只要您严格按照产品包装或者说明书上的储存条件进行储存,*可以保证其在有效期内的正常使用。一般常见储存条件有零下XX摄氏度,2-8摄氏度,常温等。特别提醒,对于某些酶类制品,如果储存条件是2-8摄氏度,不要储存在零下,否则容易失活,对于某些需要严格避光,防潮,充氮气保护的,接触空气或者过分暴露非常容易氧化或者受潮变质。
低温储存产品,运输途中冷藏问题:
对于需要低温储存的产品,我们在运输时候都会采用冷藏包装,但是部分由于外界气温过高,运输时间较长,对于普通冷藏包装,途中可能会温度升高,这些都是没有问题的,因为这种普通冷藏只适用于那些短期内(2周)高温依然稳定的产品,建议低温的储存条件,只是长期储存时候的条件,您可以放心使用。对于某些特殊的产品,如抗体,我们会采用干冰冷藏包装,确保全程低温。公司都对产品性状进行了严格的加速稳定测试,行业经验丰富。
瑞氏染液售后服务储存条件:避光、干燥阴凉处封闭贮存,严禁与有毒、有害物品混放、混运。本品为非危险 产品可按一般化学品运输,轻搬动轻放,防止日晒、雨淋!受热、受潮、受光后易丧失活力,保存期短,因此贮存和运输条件比较苛刻。
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.
Function : Transcriptional activator binding to the E-box 1 core sequence of the E-cadherin promoter gene; the core-binding sequence is 5'CAGGTG-3'.

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.
