Catalog Number: (89415-748)
Supplier: Prosci
Description: Anthrax Protective Antigen Antibody: Anthrax infection is initiated by the inhalation, ingestion, or cutaneous contact with Bacillus anthracis endospores. B. anthracis produces three polypeptides that comprise the anthrax toxin: protective antigen (PA), lethal factor (LF), and edema factor (EF). PA binds to two related proteins on the cell surface; these are termed tumor epithelial marker 8 (TEM8)/anthrax toxin receptor (ATR) and capillary morphogenesis protein 2 (CMG2), although it is still unclear which is physiologically relevant. Following PA binding to its receptor, PA is cleaved into two fragments by a furin-like protease. The bound fragment binds both LF and EF; the resulting complex is then endocytosed which allows the translocation of LF and EF into the cytoplasm. These toxins are usually sufficient to cause rapid cell death, and often the death of the organism.


Supplier: DWK Life Sciences (KIMBLE)
Description: These Caraway tubes are manufactured with tapered tips for easy collection of micro blood samples.

Supplier: WORLD PRECISION INSTRUMENTS LLC
Description: WPI™s microelectrode holder-half-cells couple fluid-filled glass micropipettes to high input impedance amplifiers. A Ag/AgCl pellet (or a silver wire) molded into the holder body provides stable potential. Electrical connection is made via male 2 mm pins or female 2 mm sockets. The pipette may be mounted axially or at right angles to the holder. Pipettes are held with screw-caps or rubber gaskets (without caps). Filling WPI microelectrode holders with electrolytes containing chloride results in stable electrode potential. Suitable electrolytes include KCl, NaCl and CaCl₂. Holders are supplied for standard WPI single capillary tubing of 1.0, 1.2, 1.5 and 2.0 mm outside Ø. (Call WPI regarding custom designs for other glass diameters.) The holder style you select will depend on your experimental application, space, and instrumentation.

Supplier: WORLD PRECISION INSTRUMENTS LLC
Description: The LWCC-M series is a MicroLWCC fiber optic low volume flow cell for UV/VIS/NIR absorbance analysis. Based on WPI's established liquid core waveguide technology, the analyte solution functions as the core of a fluid filled light waveguide. Wetted parts in the sample cell light path are PEEK, fused silica and PTFE. Optical fibers are used to transport light to and from the sample cell.

Catalog Number: (100245-582)
Supplier: Southern Biotechnology
Description: Chicken MCAM, a member of the immunoglobulin superfamily of cell surface receptors, consists of the V-V-C2-C2-C2 Ig domains. It is a single chain glycoprotein with three mRNA splice variants. One has a short cytoplasmic tail, another has a long tail, and the third seems to lack transmembrane and cytoplasmic regions. It is highly homologous to gicerin, a molecule involved in neurite outgrowth and Wilm’s kidney tumor progression in the chicken, and to the human melanoma progression molecule MUC18. Chicken MCAM is expressed by c-kit+ hematopoietic progenitor cells in embryonic bone marrow, thymocytes, and capillary endothelial cells. MCAM-expressing cells sorted from bone marrow are enriched in progenitors capable of differentiating into T cells when transferred into the appropriate thymic microenvironment. MCAM has been proposed to be involved in cellular adhesion and homing processes.


Supplier: BD
Description: These rapid plasma reagin (RPR) test kits are developed for use in large-scale testing in public health and clinical laboratories
Catalog Number: (76194-796)
Supplier: Prosci
Description: Factor XIIIa has been identified in platelets, megakaryocytes, and fibroblast-like mesenchymal or histiocytic cells in the placenta, uterus, and prostate, monocytes and macrophages and dermal dendritic cells. Anti-Factor XIIIa has been found to be useful in differentiating between dermatofibroma (almost all cases are positive), dermatofibrosarcoma protuberans (-/+) and desmoplastic malignant melanoma (-). Anti-Factor XIIIa positivity is also seen in capillary hemagioblastoma, hemangioendothelioma, hemangiopericytoma, xanthogranuloma, xanthoma, hepatocellular carcinoma, glomus tumor, and meningioma.
