近红外(NIR)荧光染料
<p></p><p>尽管大多数荧光团在光谱的可见或紫外部分中起作用,但近红外(NIR)区域对于荧光检测和成像是非常有前途的。</p><p>在红外线中,在微阵列和组织样品上观察到更少的背景荧光。这使得NIR染料成为低背景和高信噪比至关重要的理想选择。</p><p>生物组织具有700nm以上透明度的“近红外窗口”(实际值取决于组织类型)。这允许以实时,非破坏性方式对生物进行深入成像。用NIR染料标记生物分子(肽,蛋白质或其他)可以跟踪它,并研究分子在生物体中的分布。这种成像是生命科学和药物设计的重要工具。</p><p>Lumiprobe提供两种近红外荧光团:Cy7和Cy7.5</p><p>染料属于花青染料家族。两者都具有高消光系数。内部聚甲基链含有环己烷部分以增加刚性和量子产率。因此,与母体结构相比,荧光量子产率提高了20%。</p><p><br></p> <table class="table-in-product"> <tbody> <tr><th>&nbsp;</th><th>Cy7</th><th>Cy7.5</th></tr> <tr> <td class="property">Excitation wavelength</td> <td>750 nm</td> <td>788 nm</td> </tr> <tr> <td class="property">Extinction at λmaxex</td> <td>199,000</td> <td>223,000</td> </tr> <tr> <td class="property">Emission wavelength</td> <td>773 nm</td> <td>808 nm</td> </tr> <tr> <td class="property">Stokes shift</td> <td>23 nm</td> <td>20 nm</td> </tr> <tr> <td class="property">Availability</td> <td> <a href="http://www.lumiprobe.com/p/cy7-nhs-ester">NHS ester</a> (amine-reactive)<br> <a href="http://www.lumiprobe.com/p/sulfo-cy7-nhs-ester">NHS ester, water soluble</a> (amine-reactive)<br> <a href="http://www.lumiprobe.com/p/cy7-maleimide">Maleimide</a> (thiol-reactive)<br> <a href="http://www.lumiprobe.com/p/sulfo-cy7-maleimide">Maleimide, water soluble</a> (thiol-reactive)<br> <a href="http://www.lumiprobe.com/p/cy7-hydrazide">Hydrazide</a> (carbonyl-reactive)<br> <a href="http://www.lumiprobe.com/p/cy7-amine">Primary amine</a><br> <a href="http://www.lumiprobe.com/p/sulfo-cy7-amine">Primary amine, water soluble</a><br> <a href="http://www.lumiprobe.com/p/cy7-carboxylic-acid">Carboxylic acid</a><br> <a href="http://www.lumiprobe.com/p/sulfo-cy7-carboxylic-acid">Carboxylic acid, water soluble</a><br> <a href="http://www.lumiprobe.com/p/cy7-azide">Azide</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/sulfo-cy7-azide">Azide, water soluble</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/cy7-alkyne">Alkyne</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/sulfo-cy7-alkyne">Alkyne, water soluble</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/cy7-tetrazine">Tetrazine</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/cy7-DBCO">DBCO</a> (for Click chemistry) </td> <td> <a href="http://www.lumiprobe.com/p/cy75-nhs-ester">NHS ester</a> (amine-reactive)<br> <a href="http://www.lumiprobe.com/p/sulfo-cy75-nhs-ester">NHS ester, water soluble</a> (amine-reactive)<br> <a href="http://www.lumiprobe.com/p/cy75-maleimide">Maleimide</a> (thiol-reactive)<br> <br> <a href="http://www.lumiprobe.com/p/cy75-hydrazide">Hydrazide</a> (carbonyl-reactive)<br> <a href="http://www.lumiprobe.com/p/cy75-amine">Primary amine</a><br> <br> <a href="http://www.lumiprobe.com/p/cy75-carboxylic-acid">Carboxylic acid</a><br> <a href="http://www.lumiprobe.com/p/sulfo-cy75-carboxylic-acid">Carboxylic acid, water soluble</a><br> <a href="http://www.lumiprobe.com/p/cy75-azide">Azide</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/sulfo-cy75-azide">Azide, water soluble</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/cy75-alkyne">Alkyne</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/sulfo-cy75-alkyne">Alkyne, water soluble</a> (for Click chemistry)<br> <a href="http://www.lumiprobe.com/p/cy75-tetrazine">Tetrazine</a> (for Click chemistry)<br> <br> </td> </tr> </tbody> </table>
