Innovative Research Inc sheep anti tpa antibodies
Glucose deprivation (GD) induces the release of tissue-type plasminogen activator <t>(tPA)</t> from the presynaptic terminal of cerebral cortical neurons. (A) Representative micrograph of wild-type (Wt) cerebral cortical neurons maintained during 5 minutes under 25 mmol/L (+G) or 0 mmol/L (−G) of glucose and stained <t>with</t> <t>antibodies</t> against the postsynaptic dendritic marker anti-microtubule associated protein (MAP-2) (blue) and tPA (red). Green corresponds to DNA (Hoechst). Magnification × 20 in (a, e) and × 60 in (b–d) and (f–h). (B) Representative micrograph of Wt cerebral cortical neurons maintained during 5 minutes under GD and stained with antibodies against MAP-2 (blue), tPA (red), and synaptophysin (green). Arrows denote the presence of tPA-containing synaptophysin-positive presynaptic vesicles in direct contact with the postsynaptic, MAP-2-positive, dendrite. Magnification × 60. (C) Mean concentration of tPA in the culture medium of Wt cerebral cortical neurons exposed during 0 to 5 minutes to either oxygen deprivation (OD, black circles), or GD (black triangles), or oxygen and glucose deprivation (OGD; black squares), or kept under normal glucose and oxygen concentrations after medium change (baseline; white diamonds). Lines denote s.d. n=10 per condition; *P<0.05 compared with GD and OD; ^P<0.05 compared with OD and OGD; §P<0.05 compared with sister cultures maintained under physiologic conditions and with cultures exposed to either GD or OGD conditions.

(D) Representative western blot analysis of pAMPK expression in cerebral cortical synaptoneurosomes prepared from the cerebral cortex of Wt mice after transient middle cerebral artery occlusion (tMCAO) and treatment with either 0.9 mg/kg/IV of recombinant tPA (rtPA) or a comparable volume of saline solution. (E) Representative western blot analysis of the expression NR2A and NR2B subunits of NMDARs in synaptoneurosomes prepared from the cerebral cortex of Wt mice. (F) Representative western blot analysis of pAMPK expression in cerebral cortical synaptoneurosomes prepared from the cerebral cortex of Wt mice 5 minutes after tMCAO and treatment with 0.9 mg/kg/IV of rtPA alone or in combination with 2 μg of MK-801.

Figure Lengend Snippet: Tissue-type plasminogen activator (tPA) induces adenosine monophosphate-activated protein kinase (AMPK) activation in the postsynaptic terminal via N-methyl-D-aspartate receptors (NMDARs) activation. (A) Representative western blot analysis of pAMPK expression in non-ischemic wild-type (Wt) cerebral cortical synaptoneurosomes after 5 minutes of incubation with 5 nmol/L of tPA (+) or vehicle (control; −). (B) Representative microphotograph of Wt cerebral cortical neurons incubated during 5 minutes with vehicle (control; a, c, e, and g) or 5 nmol/L of tPA (b, d, f, and h), and stained with antibodies against the dendritic marker anti-microtubule associated protein (MAP-2) (red) and pAMPK (green). Magnification × 40 in (a, b) and × 60 in (c–h). (C) Representative microphotograph of Wt cerebral cortical neurons incubated 5 minutes with 5 nmol/L of tPA and stained with antibodies against synaptophysin (red) and pAMPK (green). Arrows denote examples where presynaptic synaptophysin-positive vesicles are in juxtaposition with postsynaptic pAMPK. Magnification × 100.

Article Snippet: Recombinant murine tPA, proteolytically inactive tPA (itPA) with an alanine for serine substitution at the active site Ser481 (S481A), human Lys plasmin, an ELISA kit that detects active tPA, and sheep anti-tPA antibodies (Cat # SASMTPA) were acquired from Molecular Innovations (Novi, MI, USA).
