What is FACS tube?

Designed for Fluorescence Activated Cell Sorting/ flow cytometry equipment these flow tubes are made of crystal clear polystyrene and are 12x75mm. To ensure consistent compatibility with the automated instrument the diameter and wall thickness is held to very tight tolerances.

What is Falcon test tube?

Constructed of optically clear polystyrene for easy viewing of sample. Corning™ Falcon™ Round-Bottom Polystyrene Tubes are widely used and referenced in laboratory protocols.

Can you Centrifuge FACS tubes?

The FACS Aria II and FACS Fusion can sort into 1 ml microtubes, 1.5 ml Eppendorf tubes, 12 x 75 mm test tubes, 15 ml conical centrifuge tubes, 96-well or 384-well plates. Where the sorted population consitutes from 10% to 99% of the original population, 15 ml conical centrifuge tubes should be used.

How does a FACS work?

Fluorescence-activated cell sorting (FACS) is a specialized type of flow cytometry. It provides a method for sorting a heterogeneous mixture of biological cells into two or more containers, one cell at a time, based upon the specific light scattering and fluorescent characteristics of each cell.

What is the purpose of FACS?

Fluorescence-activated cell sorting (FACS) is a technique to purify specific cell populations based on phenotypes detected by flow cytometry. This method enables researchers to better understand the characteristics of a single cell population without the influence of other cells.

Do I need FC block?

It depends on the cell population you are staining. Not all cell types express Fc receptor and, therefore, it would not be necessary. If you’re staining PBMC, it is absolutely necessary.

How many cells do you need for FACS?

For each sample, you will need between 10^5 and 10^6 cells. If you are new to flow cytometry, use the higher number of cells — to give yourself a margin for error (you always lose more cells than you expect during the staining and washing procedures).

What is a FACS machine?

What are the types of FACS?

Forward-scatter, side-scatter, and fluorescent data is collected, as in conventional flow cytometry. User-defined parameters provide information on how cells should be sorted. Based on these parameters, the FACS machine uses an electrode to impose an electrical charge on each cell.

Does FACS Count cells?

Flow cytometry provides a rapid method to quantify cell characteristics. However, most flow cytometers cannot directly provide the cell concentration or absolute count of cells in a sample.
