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.

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
