Inoculating Loops and Needles
Devices used for inoculation, serial dilution, sterile sampling, sample transfer, and microbiological sample spreading; available in materials such as polymers, aluminum, and other metals. Includes disposable and color-coded products.
Inoculating loops and needles (sometimes called microstreakers or inoculating wands) are hand-held devices for inoculating plated or tubed growth media with micro-organisms such as bacteria or yeasts prior to incubation, multiplication, and growth. The inoculum is typically streaked onto, or stabbed into, solid agar-based media, or simply introduced and dispersed into liquid media. Inoculating loops and needles are also useful for sampling and transferring small quantities of micro-organism prior to further analysis, microscopic examination, or serial dilution.
Inoculating loops and needles consist of a handle with a terminal loop or needle that is designed to pick up and transfer a small quantity of inoculum (typically 1 to 10 μL) from a donor culture to the growth medium of choice. Some loops are calibrated and color-coded to transfer semi-quantitative amounts of inoculum.
Mitegen Medium Aperture Assortment 5 each of 50, 100, 150 and 200 μm aperture Dual-Thickness MicroLoops
Simplify crystal harvesting, and obtain the best possible data from your crystals, using the most advanced lithographic cryo-loops available. Composed of X-ray transparent material, crystals can be mounted directly on the loops, reducing excess fluid, preventing damage, and making getting the crystals out of the drop easier. MiTeGen crystal mounts come in various styles and aperture sizes that allow for various approaches in choosing the right crystal mount for your application. Our mounts are hand made and inspected, packed into boxes of 20, traditionally on 18mm pins.
Apexbio Technology LLC IWP-2 686770-61-6 10mg
IWP-2 (CAS 686770-61-6) is a small molecule inhibitor targeting the Wnt/ -catenin signaling pathway through inhibition of Porcn a membrane-bound O-acyltransferase involved in palmitoylation and subsequent secretion of Wnt proteins In cellular assays IWP-2 inhibits Wnt pathway activation with an IC50 of approximately 27 nM Porcn overexpression reduces IWP-2 sensitivity confirming Porcn as the compound s molecular target In zebrafish models addition of IWP-2 did not suppress tail fin regeneration suggesting limited bioavailability in vivo Currently IWP-2 is utilized primarily for preclinical research on Wnt signaling in developmental biology and oncology

Thomas Scientific 10æl Inoculating Loop, Individual Pack, Blue, 221mm, Sterile
CELLTREAT inoculating loops and needles are made from high quality polypropylene and are available in 3 styles; needle, 1µl loop and 10µl loop. The stems are flexible and can be bent to access small volume tubes and dishes and they are color-coded for easy identification. The surface of the loops and needles are vacuum-gas plasma treated, they are packaged in peel-to-open paper/plastic wrappers and are sterile (gamma irradiated). An inoculation loop, also called a smear loop or micro-streaker, is a tool used by biologists to retrieve inoculum using the phenomenon of surface tension. The loop is used to cultivate microbes by streaking agar in a petri dish or plate for subsequent growth. The size of the loop is consistent assuring accurate and repeatable transfers. CELLTREAT L-Shaped Cell Spreaders are ideal for evenly spreading bacterial cultures and are made from high quality polypropylene. They are packaged sterile (gamma irradiated) in individual or bulk, easy-to-ope
