Experienced scientists working on antigen and antibody production, antibody engineering, lentivirus, and cell line development services for decades. >90% success rate of stable cell line generation.
Fast turnaround:
Antigen (peptide or protein) production: 3-6 weeks.
Mouse monoclonal antibody production: 20-24 weeks.
Screening phage or yeast libraries for fully human antibodies: 8-12 weeks.
Sequencing hybrioma antibody: 1-3 weeks.
Chimeric antibody production: 3-4 weeks.
Antibody humanization: 8-10 weeks.

T-cell activation, transduction, and CAR T-cell expansion: 4-5 weeks.
Confirmation of CAR expression, IFN-gamma ELISA, and cytotoxicity assay of transduced and expanded T-cells: 2 weeks.While the success rate of stable cell line generation is highly dependent on the target genes and Syd Labs can not guarantee 100% success rate, our in-house data show a success rate greater than 90%.
Fast turnaround of stable cell line development: 6-7 weeks.
We have a lot of experience in dealing with difficult-to-express proteins.Orchestrating different elements essential for optimal mammalian gene expression.
Fast return: 2-3 weeks.
Having made thousands of mammalian expression constructs and tested them in cell culture and in vivo, we are highly experienced in designing expression constructs for superb expression.100000 cells per hybridoma clone are sufficient for cloning and sequencing the monoclonal antibody variable regions (both VH and VL) and full length. Welcome to challenge us with smaller number of clonal B cells or non-viable cells for hybridoma rescue.
- Reliable results. With optimized workflow and PCR primers, we have successfully cloned and sequenced >3000 antibodies from various species in the past 10 years. Syd Labs has become a reliable CRO supplier of antibody sequencing to biotech and biopharma companies, government agencies including FDA and NIH, and universities. Clients' samples of hybridoma cell lines or clonal B cells just need to meet 2 requirements: functional antibodies are secreted by the cells; enough RNA remains.
- Save time. One may learn how to clone and sequence antibody genes by studying hybridoma antibody cloning and antibody sequencing protocols that we collected from public literature. Generally speaking, it is more difficult to clone antibody genes from rodents than other species; among isotypes, it is the easiest to clone IgG genes, especially IgG1. A couple of companies sell such kits and PCR primers. However, it takes time to become a highly efficient and experienced professional for so many lab skills and bioinformatics analysis involved in such projects. In addition, there are some samples invaluable but difficult to work. Some service suppliers spend months but could not solve the problem, just wasting clients' samples and time.
- Save money. Since we process samples from multiple clients in the same time, our cost is lower than clients'. Our low cost molecular biology reagents further save clients' cost.BS079B:
Gene synthesis of the variable regions of the recombinant scFv-Fc antibodies;
Molecular construction of the recombinant scFv-Fc antibodies;
0.04 Liter transient production of the recombinant scFv-Fc antibodies in CHO cells;
Protein A purification.Fast turnaround: 8-10 weeks in total. Our antibody humanization process involves significant computational analysis, and thus is quite efficient and requires much less trial time.
A human antibody database and a proprietary method are used for analysis and design of humanized antibodies.
Nine humanized antibodies (each combination of 3 designed heavy chains and 3 designed light chains) are constructed and produced for antigen binding confirmation and affinity measurement.
Fast turnaround: 3-6 months with our proprietary optimization algorithm.
Antibody affinity can be improved by about 10 folds after each round of antibody affinity maturation.
Denaturation and reduction followed by LC-MS (liquid chromatography-mass spectrometry) analysis.
Fast turnaround time: 1- 2 weeks.
Sample requirement: >100 ug at 1 mg/ml.Peptide mapping by LC-MS/MS can be used to determine detailed information about the peptide's sequence and post-translational modifications.
De novo antibody sequencing to obtain the intact amino acid sequence of variable and/or constant regions of monoclonal antibodies by LC-MS/MS.
Sample requirement: 3-5 mg at 1 mg/ml preferred (minimum: 2 mg at 1 mg/mL).
Fast turnaround time: 2-3 months per antibody, but may require more time depending on the complexity of analysis.
