Check if the same lab product or an alternative is used in the 5 most similar protocols
An 11-color flow cytometry panel was developed to identify epithelial
cells and leukocyte populations within dissociated kidney cells. Antibodies
include anti-CD45-FITC (HI30), anti-CD19-PE (HIB19), anti-CD11c-PerCP/Cy5.5
(Bu15), anti-CD10-BV421 (HI10A), anti-CD14-BV510 (M5E2), anti-CD3-BV605 (UCHT1),
anti-CD4-BV650 (RPA-T4), anti-CD8-BV711 (SK1), anti-CD31-AlexaFluor700 (WM59),
anti-PD-1-APC (EH12.2H7), and propidium iodide (all from BioLegend). Kidney or
urine cells were incubated with antibodies in HBSS/1%BSA for 30min. Cells were
washed once in HBSS/1%BSA, centrifuged, and passed through a 70 μm
filter. Cells were sorted on a 3-laser BD FACSAria Fusion cell sorter. Intact
cells were gated according to FSC-A and SSC-A. Doublets were excluded by serial
FSC-H/FSC-W and SSC-H/SSC-W gates. Non-viable cells were excluded based on
propidium iodide uptake. Cells were sorted through a 100 micron nozzle at 20
psi. For each sample, 10% of the sample was allocated to sort
CD10+CD45 epithelial cells as single cells,
and the remaining 90% of the sample was used to sort CD45+ leukocytes
as single cells. Single cells were sorted into 384-well plates containing
6µl 1% NP-40 with index sorting, and plates were immediately frozen and
stored at −80 °C. Flow cytometric quantification of cell
populations was performed using FlowJo 10.0.7.

Fluorescence-activated cell sorting of cryopreserved PBMCs was performed on a BD FACS Melody. Sorting baits (SARS-CoV-2 Spike) was pre-complexes with the streptavidin flurophore at a 1:4 molar ratio prior to addition to cells.

Data were acquired on a BD LSRII instrument and analyzed using FlowJo Version 9.9.6 software. NK cells were gated as follows: singlets (FSC-H v. FSC-A); Aqua-negative; low side scatter; triple negative for CD3, CD19, and CD14; and either CD56+CD16-, CD56+CD16+, or CD56-CD16+ (S9 Fig).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
