Customer Review

Based on 1 Customer Validation

Loncastuximab tesirine is a human cluster of differentiation 19 (CD19)-directed antibody-drug conjugate (ADC). The antibody portion is Loncastuximab (HY-P99711), and the drug-linker conjugate for ADC is Tesirine (HY-128952). Once bound to CD19 on the cell membrane, loncastuximab tesirine is rapidly internalised and triggers cell death. Loncastuximab tesirin induces cell apoptosis, it can be used for the research of diffuse large B-cell lymphoma.

Biological Activity

Description

In Vitro

Loncastuximab tesirine reduces cell viability and induces apoptosis of three human-derived, CD19 and CD79b-positive NHL cell lines (WSU-DLCL2, TMD8 and Ramos) and shows better effects with the combination of polatuzumab vedotin^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Loncastuximab tesirine (0.25 or 0.5 mg/kg; single dose) shows anti-tumor effects in WSU-DLCL2 xenograft models^[1].
Loncastuximab tesirine (0.33, 0.66, and 1 mg/kg; i.v. single dose) shows dose-dependently antitumor activity in Ramos xenograft models^[2].
Loncastuximab tesirine (0.1 and 0.3 mg/kg; i.v. single dose) shows dose-dependently antitumor activity in CD19-expressing Daudi xenograft models^[2].
Loncastuximab tesirine (0.3 and 1 mg/kg; i.v. single dose) results in significant, dose-dependent extension of survival in WSU-DLCL2 xenograft mouse models^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
