Plastic Discs and Annular Absorbers
” data-icon-position=”” data-hide-link-title=”0″>
Employing precision-moulding and die-cutting processes, Porvair Sciences can efficiently convert hydrophilic Vyon porous plastic into discs and annular-shaped parts to tightly toleranced specifications. These versatile approaches enable Porvair to offer high-performing, precisely manufactured products in diameters ranging from 3 mm to 1 m using any of its hydrophilic Vyon materials options, up to 4.75 mm thick. Hydrophilically treated Vyon materials have exceptional absorption and fluid-transfer properties and therefore, can be implemented as an efficient absorber with their instantaneous wetting properties. Due to the tortuous path of its porous structure, hydrophilic Vyon can efficiently filter and trap contaminants while allowing for effective delivery of drugs in various forms, such as solutions, suspensions, and emulsions. It has been tested to the most rigorous of Unites States Pharmacopeia classes and certified with a Class VI approval.
High-Performance Beam Collimators
Optical Surfaces announces a new series of high-performance beam collimators designed for modulation transfer function testing of optical systems. LW-series beam collimators incorporate a low-expansion off-axis parabolic mirror manufactured to better than λ/10 p-v surface accuracy. The optics within the collimators are secured by the use of stress-free mounts and come prealigned for optimum performance. Their off-axis design produces no central obscuration, ensuring highly efficient transmission. The all-reflecting design of LW-series beam collimators is achromatic, and their aluminium/magnesium fluoride coatings enables them to operate from the UV to the infrared without adjustment. Using low expansion glass mirror substrates, these collimators provide high operational stability and performance. Each system has an output port datum plane, giving a defined distance to the focus. Each system is also supplied with an easy-to-use alignment aid to identify the center of the focal plane. All LW-series beam collimators provide a 20-mm field, ensuring full compatibility with standard black bodies.
Biotinylated Heparan Sulfate Antibodies
AMS Biotechnology has launched two new biotinylated formats of the heparan sulfate 10E4 antibody (high and low biotin) along with a starter pack, to allow scientists to test both formats at a reduced cost. Heparan sulfate (HS) is a highly sulfated linear polysaccharide that is attached to a core protein to form HS proteoglycans on the cell membrane or in the extracellular matrix. In particular, HS has emerged as a key factor in infection by the SARS-CoV-2 virus, which is the cause of the COVID-19 coronavirus pandemic. Biotinylated antibodies are often used for the detection of low-abundance proteins. The process of biotin labeling is also frequently used as a nonradiative labeling method for proteins and as a protein purification technique. Biotin conjugation of the heparan sulfate 10E4 antibody confers many advantages by removing the need for conjugated secondary antibodies to quantify the level of detection/binding in immunological assays.
Automated Protein Purification
Automate your protein purification while maintaining sample integrity using the Thermo Fisher Scientific KingFisher Apex instrument. It automates protein isolation at low sample input volumes and produces yields high enough for LC-MS and Western downstream applications. The flexible design supports common applications as well as custom magnetic-based biomolecular separation—all with little hands-on time. It comes with user-defined, controlled cooling and heating options to maintain sample integrity. You can create and modify protocols to optimize the isolation of difficult-to-express proteins. KingFisher Apex supports 24- and 96-well plate formats for high-throughput processing. It produces consistent yields for downstream applications, such as immunoprecipitation, phage display, peptide mapping, and quantitation.
Nasal Swab for COVID-19 Testing
Melbourne-based Rhinomed Limited has provided evidence that its Rhinoswab provides superior performance for COVID-19 testing as well as making nasal sampling easier and more comfortable for users. Dual-nostril Rhinoswab has been developed to provide more comfortable, accurate, and standardized nasal sample collection that people can do themselves. Rhinoswab offers significant potential community benefits, including lessening the burden and risk to health care workers. In December 2020, the company established that Rhinoswab was comparable to existing standard-of-care nasal swabs in detecting the SARS-CoV-2 virus using RT-PCR testing, through testing at the Victorian Infectious Diseases Reference Laboratory (Peter Doherty Institute). Rhinomed has further refined the swab technology by improving the nylon flock used on the swab. Rhinoswab has recently been approved for sale in the Australian market, is listed on the Australian Register of Therapeutic Goods, and has class 1 registration with the U.S. Food and Drug Administration.
Hyperspectral Sensor Chlorophyll Fluorescence Measurements
The Hyperspec Solar Induced Fluorescence (SIF) imaging sensor from Analytik is ideal for remote sensing, particularly in plant and crop photosynthesis and climatology applications where high-resolution chlorophyll fluorescence measurements are vital. Its push broom sensor collects hyperspectral image data with 1,600 spatial pixels per line at extremely high spectral resolution (0.1 nm–0.2 nm full width at half maximum) across the chlorophyll fluorescence emission spectrum from 671 nm to 780 nm. This allows both the important oxygen-A and oxygen-B bands (O2-A and O2-B) to be exploited for more accurate insight into photosynthetic processes. With this data, environmental scientists can gain a better understanding of plant physiology and stress. The Hyperspec SIF imaging sensor is purpose-built for deployment on manned aircraft or for field-based work such as measurements from environmental observation towers.
