Antibodies for In Vivo Mouse Platelet Labeling

마우스 혈소판 연구용 항체로 정맥 내 투여 후 혈소판이 표지되며, 세포 독성이 없고 혈소판 접착 및 응집에

영향이 없습니다.

 

 

This antibody preparation contains a rat IgG derivative against the GPIbb subunit of the murine

platelet/megakaryocyte-specific GPIb-V-IX complex. The modified antibody has been optimized for the easy

and stable in vivo labelling of circulating platelets in mice. At the recommended concentration (0.1 μg/g body

weight), X-488 / X-649 is non-cytotoxic and does not interfere with platelet adhesion and aggregationin vivo.

Also, X-488 (X-649 at the recommended concentration) does not alter platelet adhesion on collagen/von

Willebrand factor in vitro. In vivo platelet labeling has been used for intravital microscopical analysis of

platelet involvement in pathological processes, such as thrombosis.1,2

An anesthetized mouse (15 g) received 1.5 μg X488 in sterile PBS intravenously and the mesenteric artery

was gently exteriorized throug a midline abdominal incision. Arterioles (35-60 μm diameter) were visualized

with a Zeiss Axiovert 200 inverted microscope (x10) equipped with a 100 W HBO fluorescent lamp source and

a CCD camera (CV-M300). Injury was induced by topical application of a 3 mm2 filterpaper saturated with

FeCl3for 10 s. Adhesion and aggregation of fluoresently labeled platelets in arterioles were monitored until

complete occlusion occurred (blood flow stopped for > 1 min). Note that adhesion of single platelets can be

detected at t=5 min.
