Frequently asked questions
Please check this FAQ first before contacting us.
Can Fine Biotech small molecule compounds be used in cell experiments?
Finebio small molecule compound series products strictly control the quality of small molecule compounds through HPLC, NMR and other technical means; It can not only be used in conventional biochemical experiments, but also meet the purity requirements for cell/animal experiments.
Why is the plant genome extraction kit not effective?
Our plant genome extraction kit is not suitable for the genome extraction of polysaccharide polyphenols samples, so you can check your plant samples if it contain polysaccharide polyphenols.
What is the difference between polyclonal and monoclonal antibodies?
| Polyclonal antibodies are a mixture of multiple antibodies targeting multiple antigenic epitopes produced by multiple B-cell clones. Monoclonal antibodies are highly homogeneous antibodies produced by a single B-cell clone, specific to a particular epitope. |
How are the peptides supplied?
| Unless otherwise specified,Peptides are supplied as freeze-dried powder of TFA salt. Peptides are shipped at room temperature or low temperature environments. Upon receiving, the peptides should be stored dry at -20 C,and better stored at -80℃. |
What is the typical turn-around time for peptide synthesis?
| For a standard peptide under 30 amino acids, delivery of the finished product is 2-3 weeks. This time could vary depending on the length and difficulty of the peptide. |
Why are peptides sold as salts?
| The free N-terminus,the ε-amino group of Lys,the guanidino group of Arg, a strong base , and the weakly basic imidazole moiety of His can form salts with acids. Most peptides contain at least one of these basic functionalities. Qute often, peptides are more soluble as salts than when they are desalted. |
What is the principle of DNA genome extraction?
After lysing cells or tissues, protease K and RNase are used to remove proteins and RNA, respectively. Subsequently, DNA is precipitated with ethanol. Following this, a silica-based material adsorption column is employed to specifically adsorb the DNA. The principle of silica-based adsorption column adsorption involves binding at high salt and low pH conditions, followed by elution at low salt and high pH conditions.
What is the typical turn-around time for peptide synthesis?
For a standard peptide under 30 amino acids, delivery of the finished product is 2-3 weeks. This time could vary depending on the length and difficulty of the peptide.
