Lorvotuzumab ELISA Kit

Lorvotuzumab ELISA Kit is a quantitative ELISA kit for detection of Lorvotuzumab.

Lorvotuzumab mertansine (IMGN901, BB10901, huN901-DM1) is an antibody-drug conjugate (ADC) composed of the cytotoxic maytansinoid derivative, DM1, conjugated to the humanized N901 monoclonal antibody (lorvotuzumab, huN901), which binds CD56 with high affinity. DM1 conjugated to lorvotuzumab via a stable disulfide SPP linker (When DM1 is attached to an antibody with the SPP linker, it is mertansine; when it is attached with the thioether linker, SMCC, it is emtansine). It was developed by ImmunoGen, Inc. Lorvotuzumab mertansine is designed for the treatment of CD56 positive cancers (e.g. small-cell lung cancer, ovarian cancer). It has been granted orphan drug status for Merkel cell carcinoma and has reported encouraging Phase II results for small-cell lung cancer (SCLC). Once bound to CD56 on the surface of the target cell, the conjugate is internalized, the linker is cleaved, DM1 is released which in turn inhibits tubulin polymerization and results in cell death. Maytansine is a natural product, originally derived from the Ethiopian shrub Maytenus serrata. Maytansine inhibits tubulin polymerization, and is approximately 200-1,000 fold more cytotoxic than the Vinca alkaloids. Maytansine is clinically active but its narrow therapeutic window precluded further clinical development. Conjugation to an antibody and intracellular delivery could take advantage of the cytotoxic potency and expand the therapeutic window leading to greater tumor cell death with less overall toxicity. The maytansine derivative DM1 was developed specifically for use in ADCs.

Target	Lorvotuzumab
Reactivity	Human
Tested Applications	ELISA
Recommended dilutions	Optimal dilutions/concentrations should be determined by the end user.
Storage	Shipped at 4 °C. Upon receipt, store the kit according to the storage instruction in the kit's manual.
Validity	The validity for this kit is 6 months.
Stability	The stability of the kit is determined by the rate of activity loss. The loss rate is less than 5% within the expiration date under appropriate storage conditions. To minimize performance fluctuations, operation procedures and lab conditions should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same user throughout.

Note	This product is for research use only. The range and sensitivity is subject to change. Please contact us for the latest product information. For accurate results, sample concentrations must be diluted to mid-range of the kit. If you require a specific range, please contact us in advance or write your request in your order comments. Please note that our ELISA and CLIA kits are optimised for detection of native samples, rather than recombinant proteins. We are unable to guarantee detection of recombinant proteins, as they may have different sequences or tertiary structures to the native protein.
