MR1 Tetramer
•
0 likes•5 views
Originally, MR1 was described in the presentation of bacteria antigens to mucosal-associated invariant T (MAIT) cells. MR1 is a ubiquitously expressed non-polymorphic MHC class I-like molecule that is conserved across species and human. MR1 can form tetramer complexes with β2-microglobulin (β2M), which is an 11.8-kD protein interacting and stabilizing MR1.https://www.creativebiolabs.net/mr1-tetramer_17.htm

ADC conjugate sites analysis
Antibody-drug conjugates employ the specific monoclonal antibodies (mAbs) to achieve targeted delivery of the conjugated cytotoxic molecules to tumor cells.
https://www.creative-biolabs.com/adc/conjugate-sites-analysis.htm
adc chemistry
As one major component of an antibody-drug conjugate (ADC), the antibody is the key for target specificity and serves as the cargo to deliver the cytotoxic drug (payload).
https://www.creative-biolabs.com/adc/antibody-design-and-conjugation.htm
ADC Biotechnology
To retain antibody bioactivity, mild, near-physiological conditions are often used for conjugation reactions. Under these conditions, endogenous amino acids such as Lys and Cys are chemically reactive and can be used as conjugation sites.https://www.creative-biolabs.com/adc/antibody-design-and-conjugation.htm
Antibody Design and Conjugation
As one major component of an antibody-drug conjugate (ADC), the antibody is the key for target specificity and serves as the cargo to deliver the cytotoxic drug (payload). A payload drug can be attached to different sites on an antibody using diverse conjugation chemistry. Multiple endogenous amino acids can serve as potential conjugation sites. However, to achieve more precisely controlled site-directed conjugations and subsequently a narrower distribution of drug-to-antibody ratio (DAR), special moieties with unique conjugation chemistries are engineered into antibody sequences in our antibody design services.

adc cd40
CD40, also known as TNFRSF5, is a type I transmembrane protein. The molecular weight of CD40 is 48-kDa and it consists of a 193 amino acid (aa) extracellular domain, 21 aa leader sequence, 22 aa transmembrane domain, and a 62 aa intracellular domain in human (90 aa in mouse).https://www.creative-biolabs.com/adc/target-cd40-122.htm
ADC Biochemical Analysis
ADC preparation involves the chemical conjugation of the three components and depending on the conjugation strategy used, this process often yields complex and heterogeneous products.https://www.creative-biolabs.com/adc/adc-biochemical-analysis.htm
ADC Antibody Screening
While conventional cancer therapies (surgery, chemo therapy, and radiation therapy) have shown some success in the battle again cancer, they are often accompanied by complex and sometimes, severe side-effects due to the lack of target specificity. To circumvent this flaw and improve the efficacy and safety of cancer treatment, targeted cancer therapies, especially antibody-drug conjugates (ADCs), have been actively exploited and they are gaining a significant amount of attention during the recent years.https://www.creative-biolabs.com/adc/adc-antibody-screening.htm

ADC Affinity Measurement
The elegant design of an antibody-drug conjugate is designated to achieve targeted delivery of the conjugated cytotoxic agents to tumor cells and drug release upon antigen binding and internalization, thus maximizing the antitumor effects while minimizing cytotoxicity to normal tissues. The efficacy of an ADC greatly depends on the specific antigen binding activities of the monoclonal antibody (mAb) portion of the molecule.https://www.creative-biolabs.com/adc/adc-affinity-measurement.htm
5t4 adc
Development of 5T4-based Bispecific ADCs
A bispecific antibody can bind two different targets or two distinct epitopes on the same target. 5T4, specifically overexpressed on the cell surface of various tumors and internalized rapidly when bound to antibody, may be used as an attractive target to develop effective immunotherapy such as bispecific antibody-drug conjugate (ADC).
