The VenaT4™ biochip is the only biochip available for studying chemotaxis, transmigration and invasion assays and is Cellix's new microflow transwell chamber.
VenaT4™趋化性研究芯片是Cellix推出的一种新型Transwell室,可以用来进行趋化(chemotaxis)、迁移(transmigration)、侵袭(invasion)研究。
The VenaT4TM biochip model combines Cellix's proprietary microfluidic flow technology for cell recruitment under shear stress with traditional transwell chamber models. Used to investigate and quantify cell recruitment to various ligands in the presence of chemoattractants contained within the microwells mimicking tissue and / or injury sites.
趋化性研究芯片结合Cellix专有的微流体技术,用于研究在剪切力下细胞的聚集。利用微孔模拟组织和/或伤口,微孔包覆化学引诱物,用于研究和量化细胞对各种配体的聚集。
The biochips contain 4 microcapillaries in parallel, each with an embedded microporous membrane with pores of 2-10um diameter (depending on application). Underneath each membrane is a microwell. See image above. The microcapillaries of the VenaT4TMbiochips are easily coated with ECM proteins using a standard yellow-tip pipette, giving the researcher greater flexibility. The VenaT4TM biochip is suitable for the following assays:
Chemotaxis Assays: Cells flowing through the microcapillary of the biochip may attach to the protein coated membrane and migrate towards the chemokine in the underlying microwell.
趋化性实验:细胞流经微流道,可能与膜上的蛋白涂布粘附,然后向底层的趋化因子迁移。
Transmigration Assays: Cells flowing through the microcapillary of the biochip may attach to the cell monolayer on the membrane and transmigrate through the cell monolayer and membrane towards the chemokine in the underlying microwell.
迁移实验:细胞流经微流道,可能与膜上的单个细胞粘附,然后穿过细胞核膜,向底层的趋化因子迁移。
Invasion Assays: Cells flowing through the microcapillary of the biochip may attach to the cell monolayer on the membrane and transmigrate through the cell monolayer and membrane into a 3D ECM in the underlying microwell.
侵袭实验:细胞流经微流道,可能与膜上的单个细胞粘附,然后穿过细胞核膜,向底层的3D ECM迁移。
The VenaT4TM biochip is suitable for use with the following:
Cell types: Leukocytes, neutrophils, lymphocytes, macrophages, monocytes, endothelial cells, epithelial cells, fibroblasts and tumour cells.
细胞种类:白细胞、中性粒细胞、淋巴细胞、巨噬细胞、单核细胞、内皮细胞、上皮细胞、成纤维细胞和肿瘤细胞。
