To demonstrate whether the temperature rise during PACT clearing influences the binding of antibody and antigen, the immunostaining was performed on 1-mm-thick Thy1-GFP-M brain section referring to the original PACT method31 (link). Before staining, the 1-mm-thick slices were cleared with 8% SDS at 37 °C, 42 °C, and 47 °C, respectively. Then the previously cleared samples were immunostained for parvalbumin and nuclei stained with DAPI. After washed in PBST for 1 day and blocked in PBS/0.1% Triton X-100/6% goat serum for 1 day, the samples were transferred to primary antibody dilutions (anti-parvalbumin antibody, Abcam, ab11427, 1:400) for 1 day followed by washing with PBST for several times, then to secondary antibody dilutions (Alexa Fluor 647 goat anti-rabbit IgG, Jackson Immunoresearch, 111-607-003, 1:400) for 1 day at 37 °C. Then the samples were nuclei stained with DAPI at room temperature for 12 hours. The samples were finally washed in PBST for several times before further incubating in 70% (wt/vol) sorbitol solution for 1 or 5 hours. For GFP immunostaining, the cleared brain slice was incubated in primary antibody dilutions (anti-GFP antibody, Millipore, AB3080, 1:200) for 2 days and secondary antibody dilutions (Alexa Fluor 633 goat anti-rabbit IgG, Invitrogen, A-21070, 1:200) for 2 days.

HEK293T cells (40–60% confluent) grown on coverslips in a 24-well plate were transfected with plasmid DNA using Lipofectamine 2000. At 48 h after transfection, cells were fixed with 4% paraformaldehyde in PBS for 10 min at room temperature. For intracellular analysis, cells were permeabilized with 0.1% Triton X-100 in PBS for 8 min. Thereafter, the cells were washed three times with PBS, blocked with 10% FBS in PBS and then incubated with anti-fBST2 pAb diluted 1:500 or anti-HA mAb diluted 1:1000 in PBS containing 1% FBS for 1.5 h at room temperature. Cells were washed three times with PBS and stained with Alexa Fluor 633 goat anti-rabbit IgG (Invitrogen) or Alexa Fluor 488 goat anti-mouse IgG (Invitrogen) diluted 1:1000 in PBS (1% FBS) along with 1 mg/ml 4,6-diamidino-2-phenylindole (DAPI) for 40 min at room temperature. The cells were then washed three times in PBS and incubated with ER-Tracker (http://www.biomart.cn/genecopoeia/index.htm GeneCopoeia, Rockville, MD, USA) for 10 min at room temperature. For surface protein analysis, the same protocol was followed, except the Triton X-100 step was omitted. Stained cells were finally washed three times with PBS and subjected to detection. Fluorescent images were obtained using a Nikon ECLIPSE Ti system with a 20× objective.

To analyze neurite outgrowth and glial wrapping, we expressed mGFP using a pan-glial driver, repo-Gal4 or repo-LexA, to label glia. The ddaE neurons were labeled by either staining for a neuronal marker, HRP, or by Gal4IG1-1>RFP. Wandering larvae at late 3rd instar stage were dissected and immunostained according to standard protocols. Adult brain dissection and immunostaining was performed following the FlyLight protocols (Janelia Research Campus, HHMI). Larval preparations and adult brains were mounted using anti-fading mounting media (VECTASHIELD®, Vector Laboratories).
Mouse monoclonal antibodies against Nrg180 (BP104, 1:200) were purchased from Developmental Studies Hybridoma Bank (DSHB, University of Iowa). Dylight 405 conjugated anti-HRP (123-475-021, 1:500) was obtained from Jackson Immunoresearch Laboratories. Rabbit anti-Ank2XL was gifted by Dr. Hermann Aberle (Max-Plank Institute for Developmental Biology).59 (link) Guinea pig anti-Pk was gifted by Dr. Jeffrey D. Axelrod (Stanford University).57 (link) Secondary antibodies were Alexa Fluor® 555 Goat anti-mouse IgG (Invitrogen A21422, 1:500), Alexa Fluor® 633 Goat anti-rabbit IgG (Invitrogen A21070, 1:500), Alexa Fluor® 555 Goat anti-Guinea pig IgG (Invitrogen A21435, 1:500).

Visualizing Zebrafish Hair Cell Dynamics

Check if the same lab product or an alternative is used in the 5 most similar protocols
Zebrafish at 6 or 14 dpf were incubated with 5 μM FM1-43FX (Invitrogen), a fixable analog of FM1-43, for 30 s, then washed three times at 5 min intervals with the rinsing solution before overnight fixation with 4% paraformaldehyde (PFA) at 4 °C. More specifically, for FM1-43FX uptake, the fish were put into baskets and bathed with labeling solution with manual agitation that resulted in fish movements forward and backward, up and down, and side to side, randomly for 30 s. Permeabilization was performed with 3% Triton-X100 (Sigma) overnight at room temperature. Blocking with 5% goat serum was carried out for 6 h at room temperature. Following this, samples were rinsed with phosphate-buffered saline (PBS) four times for 5 min. To visualize hair cells, parvalbumin 3 antiserum at 1:600 dilution was used as a primary antibody and Alexa Fluor 633 goat-anti-rabbit IgG (Invitrogen) at 1:200 dilution was used as the secondary antibody. To identify hair-bundle orientation, Alexa Fluor 633 phalloidin at 1:50 dilution was used to label actin filaments. Processed zebrafish samples were mounted and kept in antifade mounting medium (VECTASHIELD; Vector Laboratories). Images were acquired on a confocal microscope with excitation wavelengths of 488 nm for FM1-43FX and 633 nm for Alexa Fluor 633.

Renes, Erasmus MC-Josephine Nefkens Institute) diluted in the blocking solution for 12 hours at 4°C. After incubation, intestinal sections were rinsed for 3 minutes each in fresh 1X PBS, treated with blocking solution for 1 hour at room temperature, and then incubated with a 1:1000 dilution of the Alexa Fluor 633 goat anti-rabbit IgG (Cat# A21070, Invitrogen, Carlsbad, CA) in blocking solution and rinsed for 3 minutes each in fresh 1X PBS.

Check if the same lab product or an alternative is used in the 5 most similar protocols
HBVP cells were harvested and seeded at a concentration of 1.3 × 105 cells in 0.4 optical plastic flow microslides (80176, Ibidi) precoated with 1 mg/mL gelatin and incubated for 24 hours under standard culture conditions. After the initial incubation, 100 μg/mL of collagen I (354249, Corning) diluted in DMEM cell culture media was added to the slides to create a thin layer on top of the HBVP cells. After 2 hours, the media was removed and 2.5 × 105 HUVECs were seeded on top of the collagen I layer and incubated for additional 24 hours. After cell co-cultures were established, the slides were exposed to laminar (15 dyn/cm2) or pulsatile (12–15 dyn/cm2) flow for 24 hours, implementing a peristaltic pump adapted to produce different types of flow (Abello, Raghavan, Yien, & Stratman, 2022 (link)). After 24 hours, cultures were rinsed with 1x PBS and fixed for 30 minutes in 4% paraformaldehyde at room temperature. Cell cultures were immunostained with α-Smooth muscle actin D4K9N XP® rabbit monoclonal antibody (19245, Cell Signaling), followed by Alexa Fluor 633 goat anti-rabbit IgG (A21071, Invitrogen). Confocal images were obtained using a 40x objective with a W1 Spinning Disk confocal microscope, a Fusion camera, and the Nikon Eclipse Ti2-E base. Fiji image processing software was used for image analysis and fluorescence intensity quantification.

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.
