GenePharma Lentivrus mediated RNAi service

GenePharma could product high quality Lentivirus shRNA shuttle vectors suitable for in vivo research. GenePharma’s lentivirus shRNA shuttle vector are compatible with the 3 vector and 4 vector packaging systems, the clients could easily package lenti virus using the combined shRNA vectors. The service procedure is:

  1. Based on the gene information ( sequence or Gene ID) provided by the clients, we designed the shRNA sequences with special software, generally we will design four sequences.
  2. The clients choose one of GenePharma’s lentivirus shRNA vectors to construct the recombined shRNA vector.
  3. Synthesize the DNA double strand sequences and linear process the vectors, link the shRNA sequence with the vector, and screen the target recombined target, sequence the vector, and provide the recombined LV shRNA vectors to clients.

The first problem we meet for the application of siRNA is to design the sequences. Although there are quite a lot principles for the designing of published sequences and quite a few companies supply on-line design service, up to now, no software can guarantee the efficiency of the oligos designed.
Shanghai GenePharma Co, Ltd. and our collaboration laboratories have been involved in RNAi research for some time. For each specific gene target, if 4 pairs of oligos were designed and synthesized, normally you will have at least one pair showing 70% down regulation.
Our price: 2OD, PAGE purified, $89/pair
*If one single order is less than 5 pairs extra shipping fee of $40 will be charged. Payment terms are 30 days. We accept cheque or wire transfer into our USD account.
Specifications of siRNA Oligos:
Quality Control:
All our siRNA oligos undergo vigorous process monitoring and strict quality control. Length and labeling are systematically controlled by PAGE or mass spectrometry analysis. Quantity is systematically validated by UV absorbance at 260 nm.
Purification: Fully deprotected and desalted.
Purified by PAGE or RP-HPLC upon request
Length: 19 to 23 mers
Bases: RNA (A, C, G or U)
DNA (A, C, G or T)
Backbone: Phosphodiester bond
Labels and modifications: Fluorescein, biotin and phosphate: 3’ or 5’end
Other labels available upon request
Format: Single-strand RNA oligos is delivered in dry form
Storage and stability
Although oligonucleotides are stable in solution at 4°C for up to 2 weeks, we recommend storage should be at -20°C. Repetitive freeze-thaw cycles should be avoided by storing as aliquots. For long-term storage, siRNA oligos should be dried.
Oligonucleotides with fluorescent labels should be protected from light. We guarantee our oligonucleotides for six months, when stored under the above conditions.
Shipment: Shipped by express delivery, dry in individual, transparent tubes.
Oligonucleotide Technical Data Sheet
Oligonucleotides are delivered with an Oligonucleotide Technical Data Sheet, which includes oligonucleotide name, sequence, concentration, size,  purification method.
