Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunohistochemistry was carried out on 10 μm frozen sections, as previously described [13 (link)]. Muscles to be assayed by immunohistochemistry were harvested and placed in OCT (Sakura Finetek, Torrance, CA, USA) then frozen in isopentane cooled by liquid nitrogen. Muscles were cross-sectioned (10 μm) and stained using the MOM kit (Vector Laboratories, Burlingame, CA, USA) and either the AEC Peroxidase Substrate Kit (Vector Laboratories) or using fluorophore-conjugated antibodies. Antibodies used were developmental myosin heavy chain (1:25, Leica Biosystems, Teban Gardens Crescent, Singapore), CD11b (1:50, BD PharMingen, San Diego, CA, USA), CD68 (1:50, BD PharMingen), and luciferase (1:25, Promega, Madison, WI, USA). Images were acquired using a compound microscope (Zeiss, Ontario, CA, USA), processed using AxioVision software (Zeiss), and displayed using Photoshop CS4 (Adobe, Mountain View, CA, USA).

Conidium of the wild type, mutants of ΔCgena1, ΔCgena2, ΔCgena3, ΔCgena4 and their corresponding complemented strains were prepared by the method described above. The concentration of conidium was adjusted to 2 × 104 conidia/mL. A total of ten µl of conidial suspensions of each strain were dropped on hydrophobic glass slides (Fisher brand) and placed in an incubator at 25 °C [24 (link)]. Conidial germination and appressorium formation was observed under a compound microscope (Carl Zeiss, Jena, Germany) at 2, 4, 8, and 12 h hpi. The experiment was conducted three times, with at least 120 conidium counted per strain.
Invasive hyphae (IH) were induced on the onion epidermal strip according to the method as described previously [25 (link)]. IH were divided into four different types: type I, no IH development, type II, IH with one branch, type III, IH with at least two branches, but limited expansion and type IV, IH with numerous branching and extensive hyphal growth. The experiment was performed three times, and at least 50 invasive structures were observed in each treatment.

Puparia of the new species were collected on leaves of Schimasuperba from Zhejiang, Thousand Island Lake (hereafter TIL) and Gutianshan Nature Reserve, Shuangxikou village, China. No adult emergence was noticed during rearing of puparia for two weeks. Puparia were mounted following Dubey and David (2012) . The terminology for morphological structures follows Bink-Moenen (1983) , Martin (1985) and Gill (1990) . Habitus images were taken using a digital camera Canon IXUS 105 and a camera DFC 290 (Leica, Wetzlar, Germany) attached to a Leica stereomicroscope M 125 (Leica, Wetzlar, Germany). Puparial measurements and microphotographs were taken using a compound microscope (Carl Zeiss, Gottingen, Germany) from Zhejiang Agriculture and Forestry University (ZAFU). The scanning electron microscope images were taken by Hitachi TM-1000 Scanning Electron Microscope (Hitachi, Japan) from the Center of Electron Microscopy, Zhejiang University (Life Sciences Division). Adobe Photoshop 7 software was used for figure preparation. The holotype is deposited in the Insect Collections of Zhejiang Agriculture and Forestry University, Lin’an, China (ZAFU). One paratype will be deposited in the Shanghai Entomological Museum, Chinese Academy of Sciences (SEM-CAS) and the remainder in ZAFU.

Morphological Description and Molecular Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
For morphological description, specimens were removed from mounts and relaxed in a Sodium Dodecyl Sulphate-based buffer with Proteinase K, and then transferred into ethanol for observation with stereo microscopy, or into 1:1 ethanol : glycerol for imaging with a Zeiss compound microscope. Genitalia and terminal segments were dissected and mounted in temporary glycerol slide mounts, and are stored in glycerol microvials pinned with their respective specimens. Photographs of specimens were taken by using a Visionary Digital photomicrographic apparatus with Infinity optics and a Canon 60D camera, installed at the American Museum of Natural History, New York. Montage images were constructed from stacks using Helicon Focus. DNA from two paratype females was extracted according to a non-destructive protocol outlined previously (Parker and Maruyama 2013 (link)). The symbol “//” is used to separate different data labels attached to the specimens. The terminology used to describe the foveal system follows Park (1942) (link), as modified by Chandler (2001), except that the terms “mesoventral” and “metaventral” are used in place of “mesosternal” and “metasternal”, following the discussion of Herman (2013) (link).

Macrocystis and Durvillaea Taxonomy

Check if the same lab product or an alternative is used in the 5 most similar protocols
Recent collections were sampled via snorkelling from Macrocystis sp. in Wellington and collected from a large, drifting detached plant of Durvillaeaantarctica from Otago Harbour. They were immediately preserved in 95% ethanol. Specimens were examined and dissected using a Leica MZ12.5, in Wellington and drawn using a camera lucida attachment. Small appendages (mouthparts, uropods, telson) were temporarily mounted in glycerin and examined and drawn using a compound microscope (Zeiss, in Wellington) fitted with a camera lucida. The body lengths of specimens examined were measured by tracing individual’s mid-trunk lengths (tip of the rostrum to end of telson) using a camera lucida. For scanning electron microscope (SEM) imaging the specimens and appendages were dehydrated through a graduated ethanol series, acetone dried, mounted on studs, coated with gold-palladium and investigated via a SEM LEO1525.
Type material and other material examined is held at the "National Institute of Water and Atmospheric Research Invertebrate Collection at Wellington, New Zealand (NIWA) and the CeNak, Zoological Museum Hamburg.

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.
