Neace CJ, Alderete JF (2013) Epitopes of the highly immunogenic trichomonas vaginalis alpha-actinin are serodiagnostic targets for both women and men. J Clin Microbiol 51(8):2483-2490. doi: 10.1128/JCM.00582-13 PMID: 23616456

Summary: Trichomonas vaginalis is an anaerobic protozoan that is the most common nonviral causative agent for sexually-transmitted infections. The presence of T. vaginalis in men is usually asymptomatic, making it difficult to assess exposure to the organism. The authors examined sera from exposed individuals for reactivity to specific epitopes of trichomonad α-actinin. A recombinant version of trichonomad α-actinin was constructed and detected using Anti-6His (Cat. #AB-213). Some epitopes were reactive with sera from both men and women, making them potential diagnostic targets.

Premer C, Lamondin C, Mitzey A, Speth R, Brownfield M (2013) Immunohistochemical localization of AT1a, AT1b, and AT2 Angiotensin II receptor subtypes in the rat adrenal, pituitary, and brain with a perspective commentary. Int J Hypertens 2013:175428. doi: 10.1155/2013/175428 PMID: 23573410

Objective: To immunohistochemically differentiate the angiotensin receptor subtypes: AT-1ARa, AT-1ARb, and AT-2R.

Summary: Antibodies that can differentiate the three different angiotensin II receptor subtypes in the rat were used to immunohistochemically label angiotensin II receptor subtype-like immunoreactivity in the rat adrenal, pituitary, and brain. The pattern of staining corroborates mRNA, radioligand binding, and functional studies of adrenal and anterior pituitary angiotensin receptors.

Usage: Western blot (1:500), immunofluorescence (1:500), immunocytochemistry (AB-N25AP and AB-N26AP at 1:500, AB-N28AP at 1:2000).

Koch H, Zanella S, Elsen GE, Smith L, Doi A, Garcia AJr, Wei AD, Xun R, Kirsch S, Gomez CM, Hevner RF, Ramirez JM (2013) Stable respiratory activity requires both P/Q-type and N-type voltage-gated calcium channels. J Neurosci 33(8):3633-3645. doi: 10.1523/JNEUROSCI.6390-11.2013 PMID: 23426690

Summary: Pharmacological experiments have suggested that sighs and normal respiration are highly dependent on calcium currents carried by P/Q channels. Using transgenic mice missing the Cav2.1 pore-forming α1A subunit the authors demonstrate that loss of P/Q-type calcium channels results in compromised breathing, sighing, neuromodulation, and leads to early death. A neurokinin-1 receptor antibody (Cat. #AB-N33AP) at a 1:500 dilution was used for immunohistochemistry in this work.

Shia WW, Bailey RC (2013) Single domain antibodies for the detection of ricin using silicon photonic microring resonator arrays. Anal Chem 85(2):805-810. doi: 10.1021/ac3030416 PMID: 23268548

Summary: A major hurdle to clear in the fight against bioterrorism is the ability to identify various biowarfare agents. One of the more difficult substances to identify is ricin. This work describes the use of single domain antibodies to identify ricin in a microring resonator array assay. Saporin (Cat. #PR-01) along with affinity purified chicken anti-saporin (Cat. #AB-17AP) were used as controls when constructing the assay. The results demonstrate the feasibility of using microring resonator arrays for the detection of biowarfare agents.

J Neurosci 32(39):13608-13620. doi: 10.1523/JNEUROSCI.1422-12.2012 PMID: 23015450

Summary: Intrinsically photosensitive retinal ganglion cells (ipRGCs) are cells that contain the photopigment melanopsin. In this work the authors extensively characterize the M4 ipRGCs. A melanopsin antibody (Cat. #AB-N38) at a 1:10,000 dilution was used to determine the presence of melanopsin by immunohistochemistry.

Cardiovasc Res 93 Suppl 1:P209. European Society of Cardiology, Munich Germany. PMID: 909090

Summary: At the Frontiers in Cardiovascular Biology meeting in London the authors presented work examining the role serotonin and serotonin transporters play in pulmonary hypertension. Anti-SERT (Cat. #AB-N09, 1:500) was used in immunohistochemistry to detect the serotonin transporter in the myocardium.  The data demonstrate that serotonin levels in the blood and serotonin transporter levels in the myocardium are both increased in patients with pulmonary hypertension.

Lacerda CM, Kisiday J, Johnson B, Orton EC (2012) Local serotonin mediates cyclic strain-induced phenotype transformation, matrix degradation, and glycosaminoglycan synthesis in cultured sheep mitral valves. Am J Physiol Heart Circ Physiol 302(10):H1983-90. doi: 10.1152/ajpheart.00987.2011 PMID: 22345569

Summary: Calcific aortic valve disease and myxomatous mitral valve disease (MMVD) are the most commonly seen degenerative heart valve diseases. Exogenous serotonin has been shown to induce valvulopathy, but current opinion regards serotoninergic and degenerative valvulopathies as unrelated. This work investigated the relationship between serotonin synthesis and strain-induced MMVD in cultured sheep mitral valve leaflets. Anti-SERT (Cat. #AB-N09) was used in immunoblotting experiments. The results demonstrate local serotonin synthesis by mitral valves, modulation of this synthesis by tensile loading, and inhibition of serotonin results in the reduction of strain-mediated protein expression.
