Consistency of Starting Material<\/strong><\/p>\n\n\n\n<p>The amount of starting material should be consistent across all groups and samples. For biofluids, this means providing the same volume for each sample, depending on the analysis type.<\/p>\n\n\n\n<p>If you are submitting tissue or cell samples, you must provide approximately the same quantity of starting material &#8211; either tissue weight or cell number &#8211; across all groups and samples. Please note that we cannot crush or re-weigh tissue powder on your behalf. Large differences (&gt;2-fold) in starting material, or inaccurately measured tissue weights, can introduce significant bias (e.g., matrix effects) and\/or compromise result normalization (e.g., concentration relative to tissue weight).<\/p>\n\n\n\n<p class=\"has-large-font-size\"><strong>2. Required Tube Type for Tissue or Cell Samples<\/strong><\/p>\n\n\n\n<p>Tissue powder must be submitted in lysis tubes compatible with our tissue homogenizer.<\/p>\n\n\n\n<p><strong>Required product:\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/strong><br><a href=\"https:\/\/www.sarstedt.com\/en\/products\/laboratory\/screw-cap-micro-tubes-reaction-tubes\/screw-cap-micro-tubes\/product\/72.609\/\"><strong>Lysis tubes Sarstedt<\/strong><\/a><em> <\/em>&#8211; screw-cap micro tube, 2 mL<\/p>\n\n\n\n<p><strong>If samples are provided in other tube types, material loss during transfer may occur.<\/strong><\/p>\n\n\n\n<p class=\"has-large-font-size\"><strong>3. Minimum Number of Samples and Biological Replicates<\/strong><\/p>\n\n\n\n<p>We cannot accept fewer than<strong> 12 samples of the same type<\/strong>. Otherwise, we would end up analyzing more calibrators and quality controls than actual samples\u2014without considering the time required for instrument setup. We offer more than 20 types of analysis in our catalogue.<\/p>\n\n\n\n<p>Please plan for <strong>5\u20136 independent biological replicates per group<\/strong>, as metabolomic profiles represent molecular phenotypes and are inherently variable.<\/p>\n\n\n\n<p class=\"has-large-font-size\"><strong>4. Project Submission<\/strong><\/p>\n\n\n\n<p>Once the experimental design planning is complete and the samples are ready, please submit your project via our <strong><a href=\"https:\/\/metaboapp.dcsr.unil.ch\/users\/sign_up\">MetaboApp<\/a><\/strong><\/p>\n\n\n\n<p>Provide as much information as possible about your project and samples. Accurate and comprehensive metadata allows us to support you in the best possible way.<\/p>\n\n\n\n<p>As soon as you receive our feedback regarding the acceptance of your project, you may ship or bring your samples to our lab on dry ice.<\/p>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\">Many thanks for your effort and consideration!<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Requirements 1.
