SiRNA Synthesis

All oligos undergo vigorous process monitoring and stringent quality control; they are produced under ISO9000 quality standard system and HPLC purified so that purity SiRNA > 97%.

Products are quantified by spectrophotometer. Oligonucleotides are delivered with an Oligonucleotide Technical Data Sheet, which includes oligo name, sequence, concentration, orecise quantity in OD and nmols, Tm, MW, size extinction coefficient and putificatiion data.

Chemical synthesis, FAM labelling, positive and negative controls available.

services - RNAi Set.

Chemically synthetic SiRNA became rapid and effective method for gene knockdown. We recently promoted RNAi set service. You provide only gene (target) sequence and we help you to design 4 SiRNA pairs.

We guarantee at least one pair can effectively suppress gene expression. The RNAi Sets Includes :

  • 4 pairs of corresponding gene SiRNA, HPLC purification, 10 nmol
  • Negative control, 1 pair, HPLC purification, 1 OD
  • Negative control, FAM labelled SiRNA, 1 pair, HPLC purification, 1 OD
  • Positive control GAPDH SiRNA, 1 pair, HPLC purification, 1 OD

services - Vector based RNAi, Custom cloning.

GeneCust provides a set of vectors includong shRNA expression vectors, as well as corresponding negative control vector, GFP positive control vector.

We may help you to construct plasmid with insertion of targeted shRNA, and will offer accurate sequence control. You only have to tell us the target gene sequence or Gene ID number of insertion vector name, and we will send you the construct. We will provide highly purified shRNA expression vector.

Peptide Synthesis Services

GeneCust can synthesize almost any peptide you requested. Whether your peptide is short or long, we can synthesize it for you. For short custom peptides (<50-mer), we can synthesize them using our chemical method. For long custom peptides (>50-mer), we can synthesize them using our proprietary recombinant technology.

Every single custome peptide from GeneCust is analyzed by Mass spectrum and HPLC. The quality control data will be provided to the customer. For most peptides, our typical turnaround time is about 3 weeks. The delivery time may vary depends on the peptide length and difficulty. GeneCust custom peptides synthesis service is competitively priced.

The peptides catalog is available now. The price for catalog peptide is lower than for de novo synthesis. The peptides have 95% purity and are available in single package. If you order more packages you will pay less for your peptide and get higher discount.

Protein Expression and Purification service

We are pleased to launch the new protein expression and purification service.

From Gene to Protein

Starting from de novo gene synthesis, cDNA or from almost anywhere a client asks us to begin; our scientists can deliver high quality purified protein in a timely manner.

About Protein Purification

Recombinant proteins are used throughout the whole spectrum of biomedical research. Once you have large quantity of purified protein, you could conduct many downstream experiments, such as enzyme kinetics, functional and structural studies.

There are two main systems for the expression of recombinant protein - prokaryotic and eukaryotic.

Prokaryotic recombinant protein expression systems (E.Coli) have several advantages, including ease of culture, rapid cell growth and relatively simple purification procedures. However, most post-translational modifications are not added by bacteria, and most proteins become insoluble in inclusion bodies and are very difficult to recover as functional proteins.

Eukaryotic systems for the expression of protein include yeast, baculovirus cells, and mammalian cells. Advantages of these systems include high levels of expression, no inclusion bodies, and intact post-translational modifications.

Upon receiving of sequence information, our scientists would analyze the sequence to determine characteristics like molecular weight, pI, solubility, susceptibility to oxidation and hydrophobicity. Every protein is different, there is no standard way for protein expression and purification, and the protocols and strategies must be worked out for each individual protein and with its intended use in mind. Scientists at GeneCust Europe use their accumulated extensive working knowledge of purifying recombinant protein to best tailor our service to serve your research needs.
