- Parse utilise an excel sheet to determine both concentration and volume to target for their submissions to us, this includes a dilution step upon our receipt.

These excel sheets can be found on Parse's website under the kit you used (Mini/Midi/Mega) as they are different for each. Additionally, we would highly recommend to aliquot part of your samples to count the day before submission without freeze-thawing and allowing you to drop samples off earlier on the day. 
  
 ===== Sample Preparation ===== ===== Sample Preparation =====
 10x Genomics recommend a minimum viability of 70% but sample preparation is the key step in yielding good single-cell resolution data. The system is optimised to work with high quality cell/ nuclei input with accurately calculated counts. Any degradation in viability & quality or inaccurate counting is likely to end with sub-optimal results and potentially useless data. 10x Genomics recommend a minimum viability of 70% but sample preparation is the key step in yielding good single-cell resolution data.

We do not quality check or count cells for you. +Almost all failures are due to poor quality sample preparation in excess debris/ underestimated cell counts/ unsupported buffers for suspension in the cell or nuclei suspension we receive. We do not quality check or count cells for you unless required by the protocol (GEMX Flex) and even then we ask you/ a member of your lab to be present to ensure we can proceed confidently.

 +For Parse, as previously stated, the only additional advice would be to have fixed a counting aliquot alongside your main sample allowing you to count the day before and assess quality. Makes submission on the day easier and quicker as we require submission before 11am.
  
 Samples should be submitted in a clearly labelled tube (see table above) and brought on ice. Samples should be submitted in a clearly labelled tube (see table above) and brought on ice.

This may not be possible for Parse given the wholistic use of the kit but potentially utilising their Mini kit first may alleviate significant investment waste.
