Quantification of Renal EPO Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
RNA in situ hybridization was performed on 3 µm thick formalin-fixed paraffin-embedded sections of rat kidneys using the RNAscope 2.5 HD assay-brown (Advanced Cell Diagnostics) according to the user manuals 322452-USM and 322310-USM using standard conditions. EPO-mRNA was detected by the RNAScope probe Rn-Epo (Cat No. 455901) followed by semi-quantitative scoring, calculating the average count of EPO producing cells per field of view in the kidney cortex and medulla. In situ hybridization was performed with n = 8 kidneys in each group. For determination of EPO-positive cells 10 randomly chosen FOV per renal cortex or 5 randomly chosen FOV per medulla were microscopically analysed and counted [Aperio CS2 (Leica Biosystems), objective: UPlanSApo 20x/0.75 (Olympus)].

Aspergillus nidulans cells were grown on minimal medium agar plates at 30°C for 2 days. Then, the edges of colonies were cut into 5 mm squares and placed in glass dishes for observation under an inverted microscope IX-83 (Olympus). A localized heat shock was imposed on individual hypha using an IR-LEGO 1000 system (Sigma Koki) (54 (link), 55 (link)), equipped with custom-made UPlanSApo 20x/0.75 and UPlanSApo 40x/0.95 objective lens (Olympus), operating at 15 mW for 5–20 s. MetaMorph and Image J software were used for image analysis.

FRET Imaging Protocols for Live Cell Analysis

FRET images were obtained and processed under essentially the same conditions and procedures as previously described (Aoki and Matsuda, 2009) . Briefly, cells were imaged with an IX83 inverted microscope (Olympus, Tokyo, Japan) equipped with a UPlanFL-PH 10x/0.3 (Olympus), a UPlanSApo 20x/0.75 (Olympus), or a UPlanSApo 40x/0.95 objective lens (Olympus), a DOC CAM-HR CCD camera (Molecular Devices, Sunnyvale, CA), a Spectra-X light engine (Lumencor Inc., Beaverton, OR), an IX3-ZDC laser-based autofocusing system (Olympus), an electric XY stage (Sigma Koki, Tokyo, Japan), and a stage top incubator (Tokai Hit, Fujinomiya, Japan). The filters and dichromatic mirrors used for time-lapse imaging were as follows: for FRET imaging, a 438/24 excitation filter (incorporated in the Spectra-X light engine), a FF458-Di02-25x36 (Semrock, Rochester, NY) dichromatic mirror, and FF01-483/32-25 (Semrock) and FF01-542/27-25 (Semrock) emission filter for CFP and FRET, respectively. For mCherry and mScarlet-I imaging, a 575/25 excitation filter, a glass dichromatic mirror (Olympus), and FF01-624/40-25 (Semrock) emission filters were used.

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.
