]]>Thu, 11 Sep 2014 14:47:53 GMTyourphpNEO Group to build a new research centerhttps://kendallscientific.com/news/show/5.html
The center represents NEO’s longstanding commitment to technological innovation and will work toward advancements in the biological macromolecule and biomodel fields that will help commercialize innovation faster, Catherine said.

That’s very appealing, said executive team member PC Zhu. NEO’s other sites in the United States, UK, China, and India will work closely with the hub in Massachusetts. The center is not only for NEO’s in-house research, but also for NEO’s global partners and local scientists.

Innovation is the key engine of NEO Group,Laiosa said. Since 2008, the Massachusetts-based company has invested in various technical capabilities to increase R&D. We actively cooperate with our partners and license technologies from leading companies, such as EMD Millipore, and local institutes like Harvard Medical School, she said.

Biological drugs have an extremely large market in the near future, Laiosa explained. At NEO we see a tremendous opportunity in antibody development and protein expression. NEO’s MassAb, Peptide Nucleic Acids, Protein Expression (NeoXPcells) technologies can help peptide and antibody drug R&D be more efficient.



NEO officials said that the search for a specific site for the new center is under way and that the company is evaluating locations near academic institutions, including Harvard University and MIT, as well as the skilled workforce in the Boston area.

For peptides that are not soluble in water, use the following procedure:
1. For acidic peptides, use a small amount of base such as 10% ammonium bicarbonate to dissolve the peptide, dilute with water to the desired concentration. Do not use base for cysteine-containing peptides.
2. For basic peptides, use a small amount of 30% acetic acid, dilute with water to the desired concentration.
3. For a very hydrophobic peptide, try dissolving the peptide in a very small amount of DMSO, dilute with water to the desired concentration.
4. For peptides that tend to aggregate (usually peptides containing cysteines), add 6 M urea, 6 M urea with 20% acetic acid, or 6 M guanidine•HCl to the peptide, then proceed with the necessary dilutions.

Peptide storage guidelines: Lyophilized peptides should be stored in a sealed container with desiccant at -80°C (at least -20°C) in order to minimize peptide degradation. The peptide can be stored for several years under these conditions, which also prevent bacterial degradation, secondary structure formation, and oxidation.

Opening the package: Prior to opening the package containing the peptide, it is best to equilibrate the material to room temperature in a desiccator. Failure to warm the peptides can cause condensation to form on the product upon opening the bottle, reducing stability.

Weighing peptides: When weighing out a quantity of peptide, warm the package as noted above and perform the measurement as quickly as possible. Store all unused peptide at -20°C or less. Sequences containing cysteine, methionine, tryptophan, asparagine, glutamine, or N-terminal glutamic acid will have shorter shelf lives than other peptides.

Molecular Weights (MW)

 

Average MW RNA nucleotide = 340 Daltons         

MW ss RNA = (# nucleotides) x 340

 

Average MW RNA basepair = 680 Daltons

MW ds RNA = (# nucleotides) x 680

 

Average MW DNA nucleotide = 330 Daltons

MW ss DNA = (# nucleotides) x 330

 

Average MW DNA basepair = 660 Daltons

MW ds DNA = (# basepairs) x 660

 

Average MW of an amino acid = 110 Daltons

Average MW of a protein = (# of amino acids) x 110

 

 

Conversions for Protein and DNA Size and Weight

 

Average molecular weight of an amino acid = 110 Daltons

1 kg of DNA = 333 amino acids = 37 kDa protein

10 kDa protein = 270 bp DNA

100 pmol of 1 kDa protein = 100 ng

 

1 kb of ds DNA = 6.6 x 10/5 Daltons

1 kb of ss DNA = 3.3 x 10/5 Daltons

1 kb of ss RNA = 3.4 x 10/5 Daltons

 

Average weight of a nucleotide = 330 Daltons

1 µg of 1000 bp DNA = 1.53 pmol (3.03 pmol of DNA ends)

1 pmol of 1000 bp DNA = 0,66 µg

 

1 A260 unit of ds DNA = 50 µg/ml

1 A260 unit of ss DNA = 33 µg/ml

1 A260 unit of ss RNA = 40 µg/ml
