High-purity
Plasmid Mini Kit (Spin-column)
Spin columns for plasmid miniprep can
also be used for DNA extraction from gels and PCR product
cleanup. Ask us for buffer recipe if you buy spin columns
only.

and do not need ethanol precipitation.
- Best quality binding solution,
without sodium iodide and perchlorate, has no inhibition
to down-stream reactions.
- The binding buffer DB is yellow,
which is convenient for monitoring the pH when melting
gel.

Viral DNA/RNA Rapid Extraction Kit(Spin-column)
This procedure represents a
well-established technology for viral DNA/RNA
purification. Viruses are first lysed and
RNases activities are inactivated by innovative
binding solution/protease K. This technology
combines the selective binding properties of a
silica-based membrane with the speed of microspin
technology. A specialized high-salt buffer system
allows RNA /DNA to bind to the silica
membrane. Then, the sample is applied to a
Mini spin column, where the RNA/DNA binds to the
membrane and contaminants are efficiently washed
away by novel washing solution. Finally,
High-quality RNA/DNA is eluted by low-salt RNase-free
water from silica-based membrane.
Feature and benefits
The usage of toxic phenol
reagent and ethanol precipitation are eliminated
Generates high-quality
DNA/RNA for downstream application
Stable, comparable DNA/RNA
yield with high quality absorbing membrane,
accomplish rapid and efficient purification with
excellent reproducibility

Coagulated
Blood DNA Mini-extraction Kit(Spin-column)
Principle
The kit applies special columns to separate blood
blots according to the characteristics of whole blood
to rapidly isolate DNA. First erythrocyte lysis buffer
removes DNA-free erythrocyte. Nuclear lysis buffer
splits leukocyte and DNA is released. Then protein
precipitation buffer precipitates and removes protein
selectively. Last the purified DNA is precipitated by
isopropanol, and then DNA is dissolved in DNA
dissolving buffer.
Features
1.Not contain phenol and other harmful compounds not
required.
2.Simple and rapid. One preparation can be completed
in 1 hour.
3.Stable result and high yield (the typical yield of
10ml whole blood about 150-500μg), high purity, the
value of OD260/OD280 achieving 1.7-1.9. The Length of
the genomic DNA is 50kb-150kb ,which can be applied to
PCR，Southern-blot and digestions directly.

Nucleic
Acid Stain
Description
UltraPower Nucleic Acid Stains are a kind
of new generation of fluorescent nucleic acid gel
stains designed to replace the highly toxic ethidium
bromide (EtBr). UltraPower Nucleic Acid
Stains is nontoxic and highly sensitive than EtBr.
Gels can be visualized in UV transilluminator or
Visible Light Transilluminator.
Features
- Safety: is
non-toxic and non-carcinogenic.?
- Ultrasensitivity: allows
the visualization of as little as 20pg dsDNA,
around 5-10 times more sensitive than EtBr in UV
transilluminator and 8-20 times more sensitive
than EtBr in Visible Light Transilluminator.
- Convenience:
no need to rinse or wash gels. Add stain before
load samples. Visualize gels in UV
transilluminator. Or in Visible Light
Transilluminator to avoid UV damage on DNA/RNA.
- Wide range: suitable
for agrose gel or PAGE
- No effect on
downstream experiments such as RT, PCR,
enzyme digestion, and ligation.
- Strong signal and
no background.
- Low cost: 1ml
UltraPower Nucleic Acid Stain is
sufficient to load 10,000 samples.

D-Luciferin,
Potassium Salt
Description:
The pigment
luciferin, a low molecular weight organic compound
isolated from fireflies, has been isolated in a
variety of bioluminescent organisms. Light can be
produced by oxidation of luciferin but the reaction
rate is extremely slow in the absence of the enzyme
luciferase and the cofactor ATP. Luminometers and
optical microscopes have been developed to detect
light emitted from the two-step luciferase-catalyzed
reaction. The protein Luciferase can be transiently or
stably expressed in cells and organisms. Thus,
luciferase and luciferin have been widely used in in
vitro and in vivo luciferase reporter assays detecting
gene expression and detecting the level of cellular
ATP in cell viability assays or for kinase activity
assays. The applications of luciferase and luciferin
are still expanding.
We provides three forms of D-luciferin: D-luciferin
free acid, D-luciferin potassium salt, and D-luciferin
sodium salt.
