Gibbons DD, Southerland EM, Hoover DB, Beaumont E, Armour JA, Ardell JL (2012) Neuromodulation targets intrinsic cardiac neurons to attenuate neuronally mediated atrial arrhythmias. Am J Physiol Regul Integr Comp Physiol 302(3):R357-R364. doi: 10.1152/ajpregu.00535.2011 PMID: 22088304

Summary: Cardiac arrhythmias can be generated by excessive activation of specific inputs to the intrinsic cardiac nervous system. The authors sought to determine whether subpopulations of neurons were responsible for this activation, and therefore potential therapeutic targets. A series of studies were done following electrical stimuli to the mediastinal nerves. Choline acetyltransferase levels were assessed using anti-ChAT (Cat. #AB-N34) in immunohistochemistry. The data suggest activation of certain neurons by mediastinal nerve stimulation results in atrial arrhythmias leading to atrial fibrillation.

Summary: In this work the authors administered 100 ng SSP-SAP (Cat. #IT-11) into the intrathecal space of rats (saporin, Cat. #PR-01, was used as a control). Lesioned animals displayed decreased carrageenan-induced mechanical allodynia, and carrageenan-induced phosphorylation of Akt was blocked throughout the spinal cord gray matter. Anti-NK-1 (Cat. #AB-N33AP) was used for immunohistochemistry.

Q: I have a question regarding your antibody to NGF (p75) receptor antibody (Cat. #AB- N01AP). Could you please tell me how you determined that it is a blocking antibody? Has this information been published?

A: We list on our website that one application for this antibody is for blocking the function of nerve growth factor receptor. This information was presented in an abstract at the Society for Neuroscience Meeting held in 1994.

Asano Y (2012) Age-related accumulation of non-heme ferric and ferrous iron in mouse ovarian stroma visualized by sensitive non-heme iron histochemistry. J Histochem Cytochem 60(3):229-242. doi: 10.1369/0022155411431734 PMID: 22108647

Summary: The mammalian ovary engages in continuous growth and cellular differentiation as long as the animal is capable of reproduction. During these processes iron ions are released from heme structures; these ions are capable of generating free radicals. The purpose of this study was to investigate non-heme iron distribution in ovarian tissue, and how this distribution changes during aging. Lipid peroxidation was monitored by immunohistochemistry using anti-conjugated malondialdehyde (Cat. #AB-T090). The data indicate that increasing oxidative stress, non-heme iron accumulation in ovarian stromal tissue, and aging are related.

Fiedler J, Strauss G, Wannack M, Schwiebert S, Seidel K, Henning K, Klopocki E, Schmugge M, Gaedicke G, Schulze H (2012) Two patterns of thrombopoietin signaling suggest no coupling between platelet production and thrombopoietin reactivity in thrombocytopenia-absent radii syndrome. Haematologica 97(1):73-81. doi: 10.3324/haematol.2011.049619 PMID: 21933853

Summary: Lower than normal blood platelet counts result from a congenital disorder called thrombocytopenia (thrombocytopenia absent radii syndrome, or TAR). Recent work indicates a complex pattern of inheritance, and possibly that TAR is at least a digenic disorder. The authors performed an extended study investigating signal transduction via immunoblotting, gel electrophoretic shift assays, and flow cytometry. One of the antibodies used was anti-p70 S6K (Cat. #AB-241). The authors conclude that there are defects in both platelet production and function in TAR.

Cereb Cortex 22(7):1690-1697. doi: 10.1093/cercor/bhr254 PMID: 21914633

Summary: Verifying the presence of D-serine in astrocyte vesicles would help resolve whether astrocytes produce rapid gliotransmitter exocytosis for the purpose of neuromodulation. In one of a series of experiments the authors looked at D-serine levels with anti-L-glutamate (Cat. #AB-T08). The results suggest that domains of astrocytes can acquire local Ca2+ increases that trigger glutamate and D-serine release.

Chen S, Badea T, Hattar S (2011) Photoentrainment and pupillary light reflex are mediated by distinct populations of ipRGCs. Nature 476:92-95. doi: 10.1038/nature10206 PMID: 21765429

Summary: Intrinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment Melanopsin and regulate a wide array of light dependent physiological processes. Genetic ablation of ipRGCs eliminates circadian photoentrainment and severely disrupts the pupillary light reflex (PLR). Scientists showed that ipRGCs consist of distinct subpopulation that differentially express the Brn3b transcription factor, and can be functionally distinguished. Brn3b-negative M1 ipRGCs innervate the suprachiasmatic nucleus (SCN) of the hypothalamus, whereas Brn3b-positive ipRGCs innervate all other known brain targets. Selective ablation of Brn3b-postive ipRGCs severly disrupts the PLR, but does not impair circadian photoentrainment. The scientists concluded that molecularly distinct subpopulations of M1 ipRGCs, which are morphologically and electrophysiologically similar, innervate different brain regions to execute light-induced functions. A dilution of 1:1000 of Anti-Melanopsin (Cat. #AB-N38) was used for immunohistochemical analysis of retina sections.

Summary: This work demonstrates the creation of a variety of constructs containing specific defined conjugation sites. One use for these molecules is to create homogenous antibody conjugates‚ meaning the properties of these conjugates can be quantitatively evaluated. Having greater control of such conjugations is essential if these types of constructs are to move toward use as therapeutics. The authors created an anti-Her2 Fab-saporin molecule and tested it in vitro. Analysis by western used anti-SAP-HRP (Cat. #AB-15-HRP) to detect the conjugated molecule.
