Apexbio Technology LLC 5-Carboxyfluorescein diacetate N-succinimidyl ester 150206-05-6 5mg
5-Carboxyfluorescein diacetate N-succinimidyl ester (CAS 150206-05-6) is a fluorescent cell-permeable dye It is designed to enable stable cell labeling by facilitating intracellular conversion and covalent attachment to cellular amines 5-Carboxyfluorescein diacetate N-succinimidyl ester exerts its activity through membrane permeation intracellular esterase-mediated cleavage of acetate groups and subsequent covalent coupling to intracellular targets resulting in persistent fluorescence through cell division Based on these properties 5-Carboxyfluorescein diacetate N-succinimidyl ester holds research potential in tracking lymphocyte migration analyzing cell proliferation and investigating cell dynamics and interactions in various in vitro and in vivo experimental models
Medchemexpress LLC B7-H4 Human Biotin 100ug | 100ug
The B7-H4 protein acts as a negative regulator inhibiting T cell-mediated immune responses including activation proliferation cytokine production and cytotoxicity When expressed on tumor macrophages it cooperates with regulatory T cells to suppress tumor-associated antigen-specific T cell immunity B7-H4 Protein Human (Biotinylated HEK293 His-Avi) is the recombinant human-derived B7-H4 protein expressed by HEK293 with C-Avi C-His labeled tag
Medchemexpress LLC PCSK9 Human Biotin 20ug
The PCSK9 protein is an important regulator of plasma cholesterol homeostasis affecting LDL receptor family members such as LDLR and VLDLR It promotes their intracellular degradation and enhances hepatic LDLR degradation through non-proteolytic mechanisms PCSK9 Protein Human (Biotinylated V474I G670E HEK293 Avi) is the recombinant human-derived PCSK9 protein expressed by HEK293 with C-Avi labeled tag and V474I G670E mutation

Biotium CF790 Succinimidyl Ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Near-infrared fluorescent CF790 dye has excitation/emission at 784/806 nm.
