Fitc conjugated anti rabbit antibody

Manufactured by Jackson ImmunoResearch
Sourced in United States

The FITC-conjugated anti-rabbit antibody is a laboratory reagent used for the detection and identification of rabbit-derived proteins or antigens. It consists of a fluorescein isothiocyanate (FITC) molecule covalently attached to an antibody specific for rabbit immunoglobulins. This reagent can be used in various immunoassay techniques, such as immunofluorescence microscopy, flow cytometry, and Western blotting, to visualize and localize rabbit-derived targets.

For intracellular staining, cells were surface stained and fixation/permeabilization buffers (eBioscience) protocol was followed. Intracellular antibody used was PTEN (Cell Signaling) followed by FITC conjugated anti-rabbit antibody (Jackson ImmunoResearch). For intracellular phosphoflow staining, cells were surface strained then fixed in 2% PFA for 30 min at RT and permeabilized with 90% methanol for 30–60 min on ice. Cells were washed in PBS then stained for AKT, Phospho-AKT Thr308 and Phospho-AKT Ser473 (Cell Signaling) followed by FITC conjugated anti-rabbit antibody (Jackson ImmunoResearch). Samples were analyzed on an LSR Fortessa cytometer or sorted using a FACS Aria II (BD Biosciences). Data were analyzed with FlowJo software (Tree Star).

At determined time, the different groups of RPCs were xed with 4% paraformaldehyde (PFA). After blocking with 10% normal goat serum (Sigma-Aldrich), the cells were incubated with one of the following primary antibodies: Ki67, Nestin, GFAP, β-III-tubulin, Recoverin, Rhodopsin (Abcam), Crx (Omnimabs) 4 °C overnight. Then they were labeled with the corresponding secondary antibodies: Alexa 488-conjugated anti-mouse, Cy3-conjugated anti-mouse or FITC-conjugated anti-rabbit antibodies (Jackson). Finally, cells were counterstained with DAPI nuclear stain and observed by uorescent microscope (Leica, Germany). The positive ratio was calculated with (immunepositive cells/DAPI stained cells in the eld) × 100% by ImageJ software.

To determine the DNA content and mitotic index by flow cytometry, cells were cultured in 10 cm dishes in the presence of the appropriate inhibitors. Culture media was then collected and the remaining cells harvested by trypsinisation. Cells were then pelleted and washed in PBS before finally being resuspended in 150 μl PBS plus 350 μl 100% ice-cold ethanol. Cells were then stored at −20°C for at least 16 hr. Fixed cells were washed twice in PBS and incubated with rabbit anti-phospho-histone H3 (Ser10)(Millipore) diluted 1:1000 in PBS for 1 hour at 4°C. Following a PBS wash, cells were then incubated with a FITC-conjugated anti-rabbit antibody (Jackson Immunoresearch) for one hour at 4°C. Cells were again washed in PBS and resuspended in 500 μl PBS containing 40 μg/ml propidium iodide, 50 μg/ml RNase A.

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.
