Plant hemoglobins: Oxygen handlers critical for nitrogen fixation
Hemoglobins, key components of our blood, are ancient proteins with well-known roles in oxygen transport and respiration in animals. Hemoglobins are also present in plants and bacteria, but until now the physiological role of plant hemoglobins has been unclear. A group of researchers reveal this week that one such mysterious plant hemoglobin serves to assist in the fixation of nitrogen in the roo...Nature's process for nitrogen fixation caught in action
Nitrogen gas is converted to ammonia fertilizer by a chemical process that involves high temperature and high pressure. Nature does the same thing at ambient temperature and pressure. The process, called nitrogen fixation, is essential to life as it provides nutrients to plant life. A research team from Utah State University, Virginia Tech, and Northwestern University asked whether the bio...LEUCOPERM Suspension fixation and permeabilization solution from GeneTex
Description:Reagent A - Fixation medium LEUCOPERM reagents are intended for fixing cells in suspension with Reagent A and then permeabilising the cells with Reagent B. This procedure gives antibodies access to intracellular structures and leaves the morphological scatter characteristics of the cells intact. Specific formulations reduce background staining and all...Mouse, normal organs, perfusion fixation from IMGENEX
Description:...Immunofixation Gel Kit, requires IF100 from CHEMICON
Description:Immunofixation Gel Kit, requires IF100...eBioscience IC Fixation Buffer 125 ml from eBioscience
Description:eBioscience Intracellular (IC) Fixation Buffer, used in conjunction with eBioscience Permeabilization Buffer (Cat. No. 00-8333), can be used to fix and permeabilize cells prior to performing intracellular staining of cytokines and other cytoplasmic and/or nuclear antigens. These solutions have been specially formulated for reducing non-specific staining by fluorochrome-labelled antibodies and inc...Fixational eye movement responsible for visibility
Professor Susana Martinez-conde and her research team from Barrow Neurological Institute in Phoenix have found that Microsaccades, which are rapid// movements occurring inside the eye even when the person is looking at a fixed point, are also responsible for proper visibility. Even when we are gazing at a fixed object our eye are continuously moving which make things visible and if t...Globe Fixation Ring with Swivel
Description:Titanium. Designed to fixate the eye during refractive surgery procedures. The two-sided ring can easily be pivoted to engage the pointed or smooth side on the eye. Ideal for applying pressure to the eye to increase internal pressure while making incisions. Dull finish....Thorton Fixation Ring with Handle
Description:Fixation ring with atraumatic teeth provides excellent stabilization and pressure on globe. Round knurled handle with dull finish....
