Ic002f

Manufactured by R&D Systems
Sourced in United States

The IC002F is a laboratory instrument designed for immunocytochemical (ICC) and immunohistochemical (IHC) staining procedures. It is a compact, automated system that performs slide-based staining of fixed cells or tissue sections. The IC002F can handle multiple sample slides simultaneously and automates the critical steps of the staining process, including reagent addition, incubation, and washing. This equipment is intended for use in research and clinical laboratory settings to facilitate standardized and reproducible immunostaining workflows.

For the flow cytometry assay, both hTDSCs and dTDSCs at P3 were used. 1 × 106 cells of each group were incubated with 1 mg of phycoerythrin-conjugated or fluorescein-isothiocyanate-conjugated monoclonal antibodies (R&D Systems) at 4 °C for 1 h. Anti-CD34 (sc-7324; Santa Cruz Biotechnology, Santa Cruz, CA), anti-CD31 (ab33858; Abcam, Cambridge, UK), anti-CD44 (BD550974; BD Bioscience), anti-CD45 (BD559135; BD Bioscience), and anti-CD90 (BD554898; BD Bioscience) were the antibodies used in this study. Phycoerythrin-conjugated or fluorescein-isothiocyanate-conjugated isotype-matched IgG1 were used as negative controls (IC002P or IC002F; R&D Systems). The stained cells were washed with ice-cold PBS containing 2% BSA before analysis using the LSRFortessa flow cytometer (Becton Dickinson, San Jose, CA). About 1 × 104 events were counted for each sample. The percentage of cells with a positive signal was calculated using the WinMDI Version 2.9 program (The Scripps Research Institute, La Jolla, CA).

Fibrosis Induction and Quantification in Human Tubular Epithelial Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
A single-cell suspension was prepared by filtering the homogenate using a 40-μm pore cell strainer (BD Pharmingen, San Jose, CA, USA). Cells were incubated with Fc Block anti-CD16/32 (IC1918F, BD Pharmingen) and stained with fluorescein isothiocyanate-conjugated anti-fibronectin or isotype control (IC002F, R&D Systems) for 1 h. Fibronectin-positive cells and E-cadherin-positive cells were analyzed using a BD FACS Diva instrument (version 8.0; BD Biosciences). Fibrosis was induced in hTECs with 2 ng/mL rTGF-β (R&D Systems) for 48 h. To evaluate the role of CCL8 in fibrosis, rTGF-β-stimulated hTECs were simultaneously treated with an anti-CCL8 monoclonal antibody (50 or 100 ng/mL; Invitrogen). To quantify cell fibrosis and adhesion, cells were harvested and stained with antibodies against fibronectin (Invitrogen) and E-cadherin (R&D Systems) according to the manufacturers’ protocols. Apoptosis and necrosis were quantified by flow cytometry using an annexin V/propidium iodide assay. hTECs stained with propidium iodide and FITC-conjugated annexin V were incubated for 30 min in the dark, followed by analysis with the BD FACS Diva instrument.

Phycoerythrin (PE) or fluorescein isothiocyanate (FITC) (BD Biosciences)-conjugated mouse anti-rat monoclonal anti-CD44 (550974; BD Biosciences) and anti-CD90 (551401; BD Biosciences) were used. PE- or FITC-conjugated isotype-matched IgG1 were used as negative controls (IC002P or IC002F, R&D systems, Inc., Minneapolis, US). TDCs (5 × 105; P1) were incubated with 1 μg of antibodies away from the light for 45 min at room temperature. After washing and centrifugation at 4000× g for 5 min, the cells were resuspended in 300 μL of ice cold PBS (with 10% FBS and 1% sodium azide) and subjected to fluorescence-activated cell sorting (FACS) analysis (BD Biosciences). A BD FACSCalibur™ system (BD Biosciences) was used to calculate the percentage of cells with positive signals.

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.
