1. Antibodies
Antibodies against Macrophage/Microglia-specific Protein Iba1
Anti Iba1 polyclonal antibodies, Rabbit   (Iba1: ionized calcium binding adapter molecule 1)
Calcium ions are known to be one of the most important signal mediators in all cells including central nervous system (CNS) cells. Calcium
ions exert their signaling activity through association with various calcium binding proteins, many of which are classified into a large protein
family, the EF hand protein family.
Iba1 is a 17-kDa EF hand protein that is specifically expressed in macrophages/ microglia and is upregulated during the activation of these
Wako has launched rabbit polyclonal antibodies were raised against a synthetic peptide corresponding to the Iba1 carboxy-terminal sequence,
which was conserved among human, rat and mouse Iba1 protein sequences.     These antibodies are specifically reactive to microglia/
macrophages, are appropriate for immuno-double staining of brain tissues and cell culture in combination with monoclonal antibody to GFAP,
which specifically reacts to astrocyte.
Specificity :
     Specific to microglia and macrophages, but not cross-reactive with neurons and astrocytes.
     Reactive with human, mouse and rat Iba1.

Antibodies against Vesicular Glutamate Transporters
Anti Rat VGLUT, Rabbit
L-Glutamate is an excitatory chemical transmitter that plays an essential role in neuronal plasticity, behavior, learning and memory in the
central nervous system. On the other hand, VGLUTs play an essential role in glutamate signal output through vesicular storage of
L-glutamate. Three kinds of VGLUTs have been identified so far. Recent studies have demonstrated that VGLUTs are also expressed in
peripheral cells such as stomach, intestines, pancreas and testes. In particular, the discovery that glutamate is co-localized with glucagon in
secretory granules in_cells of islets of Langerhans has been noted for new mechanism of blood glucose control. Anti Rat VGLUT, Rabbit can
detect glutamatergic central nerves, peripheral nerves and nonneural cells.
Both antibodies are applicable to immunocytochemistry, immunoelectron microscopy and western blotting.

P-glycoprotein and multi-drug resistance-associated protein 1. This enabled Agosterol A to inactivate
protein-mediated pump which extrudes chemotherapeutic drugs out of the cell membrane of multi-drug
resistant cancer cells. Agosterol A is a promising substance which completely reverses cancer multi-drug

Plasmaprekallikrein circulates in the blood as the zymogen of
plasma kallikrein, and is activated by factor XIIa to form plasma
kallikrein. Plasma kallikrein releases bradykinin from high
molecular weight kininogen. Furthermore, it has been reported
that plasma kallikrein activates factor XII, pro-urokinase and
plasminogen. Plasma kallikrein is also known to cause neutrophil
aggregation and elastase release. These observations suggest that
plasma kallikrein has many function. PKSI-527 inhibited plasma-
kallikrein (PK) with a Ki value of 0.81µm is a great potential tool
in elucidating the significance of PK.

7. Synthetic Retinoids
Biologically Active Substances
Retinoids, retinoic acid and its bio-isosters, regulate many biological functions such as cell differentiation, proliferation and embryonic
development in vertebrates, through binding to and activation their specific nuclear receptors. Five representative synthetic retinoids are
available for researcher investigation in signal transduction system through retinoids receptors.

Quenched Fluorescence Substrate Assay of PTP Activity
Fluorospark™ PTP Assay Kit
Cat. #299-55601 100 tests    -sorry, discontinued... -
-20°C, D/I
Phosphorylation and dephosphorylation of protein tyrosine in signal transduction is thought to play a critical role in regulation of physiological
phenomena as immune response, oncogenesis, differentiation, apoptosis, and cell proliferation. Many tyrosine kinases have been cloned and
characterized to understand signaling pathways by phosphorylation, whereas, little is known about the roles of Protein Tyrosine Phosphatase (PTP).
Fluorospark™ PTP Assay Kit consists of all the essential buffers and reagents including quenched fluorescent phosphrylated peptide substrate for
PTP, allowing a homogeneous fluorescent PTP activity assay with a fluorescence microplate reader and a standard fluorometer. The sensitivity by
the standard assay protocol is at 1 pmol or the less, compatible to those of the assay using radio actives.
  1. High sensitive measurement of PTP activity at sub-pico moles, compatible to that with RI labeled peptide substrate.
  2. Allowing a homogeneous assay of PTP, which is simple, rapid, and applicable to high throughput screening assay as well as that using
     fluorescence microplate reader.
  3. Allowing the PTP assay even in the presence of phosphate because of indirect measurement of released phosphate.

12. Mg2+-selective Fluoroionophore
Cat. #110-00711   1 mg
        #116-00713   5 mg
-20°C, D/I, Solid
Dynamic distribution of Mg2+ in living cells can be done due to
selective recognition of Mg2+ by KMG-20-AM. KMG-20-AM is
much less reactive to Ca2+ than Mg2+.

KMG-20-AM enables accurate measurement of Mg2+ because it has
very much low affinity to Ca2+ compared to Mg2+.
Appearance: Brown, powder
Assay (HPLC): 95+ %
 1. Mg2+-imaging without interference of Ca2+
 2. Precise observation of Mg22+ distribution by Fluorescent
 3. Direct observation of Mg2+ ion dynamics in living cells
