4×SDS-PAGE solution for resolving gel Gene Protein

4×SDS-PAGE solution for resolving gel Gene Protein

Product name:4×SDS-PAGE solution for resolving gel

Specifications:100ml/250ml/500ml

Product description:
SDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis, is a technique widely used in biochemistry, forensics, genetics and molecular biology to separate proteins according to their electrophoretic mobility. SDS gel electrophoresis of samples having identical charge per unit mass due to binding of SDS results in fractionation by size and is probably the world's most widely used biochemical method.

pBR322 DNA General description

pBR322 DNA General description


DNA vectors

pBR322 DNA General description

Plasmid pBR322 was one of the first multipurpose cloning vectors constructed for use in E. coli. This plasmid is derived from the ColE1-type plasmid pMB1 and shares the same type of replication mechanism and controls as ColE1 and relatives. Plasmid pBR322 confers resistance to ampicillin and tetracycline. The plasmid sequence has been published.

Plasmid pBR322 was one of the first multipurpose cloning vectors constructed for use in Escherichia coli. This plasmid and derivatives have been used for a number of purposes including cloning, selection and expression of recombinant molecules, construction of shuttle vectors and vectors for nucleotide sequencing, studies of elements involved in gene expression, as plasmid DNA standards, and as a model system for studies on prokaryotic plasmid replication.

About the HTLV Test kit


The human T-lymphotropic virus type I (HTLV-1) is a human retrovirus that is known to cause a type of cancer, referred to as adult T-cell leukemia and lymphoma, and a demyelinating disease called HTLV-I associated myelopathy/Tropical spastic paraparesis (HAM/TSP). HTLV-I is one of a group of closely related primate T lymphotropic viruses (PTLVs). Members of this family that infect humans are called Human T-lymphotropic viruses, and the ones that infect old world monkeys are called Simian T-lymphotropic viruses (STLVs). To date, four types of HTLVs (HTLV-I, HTLV-II, HTLV-III, and HTLV-IV) and four types of STLVs (STLV-I, STLV-II, STLV-III, and STLV-V) have been identified. The HTLVs are believed to originate from intraspecies transmission of STLVs. The original name for HIV, the virus that causes AIDS, was HTLV-III; this term is no longer in use . The HTLV-1 genome is diploid, composed of two copies of a single-stranded RNA virus whose genome is copied into a double-stranded DNA form that integrates into the host cell genome, at which point the virus is referred to as a provirus. A closely related virus is bovine leukemia virus BLV.

The nature of catechin

 Catechins(catechin) are widely distributed in plant kingdom, the Acacia catechu, gambir bark abounds with tannins.
Catechins and their oxidation products are hydrocarbon oxygen ternary compound, is made from sugar through a series of enzymes, shikimic acid, by the formation of benzene compounds, the synthesis of catechin.
Catechins has obvious characteristics of phenol, can cause the heavy metals and protein precipitation, therefore, is a kind of phenol content. Phenol content because can make the protein to precipitate, has the size of raw hides tanning into leather performance, so also called tannins or tannin substances.
Catechin and some typical plant tannins (gallic tannin, etc.), compared the performance of the tanning is weaker.
Flavan derivatives. Widely exists in plants, including crystallization water from water/acetic acid needle crystal. Melting point of 93 ~ 96 ℃; Instead of containing water of crystallization of crystalline melting point of 175 ~ 177 ℃. Polarimetric + 16 ° ~ + 18.4 °. Its raceme also assumes the needle crystal, melting point of 212 ~ 216 ℃. Slightly soluble in cold water, ether, soluble in hot water, ethanol, glacial acetic acid and acetone, insoluble in benzene, chloroform and petroleum ether. Catechu essence of cis stereo heterogeneous surface catechu (epicatechin) also widely exists in plants, melting point 242 ℃, polarimetric [alpha] D - 68 ° (ethanol).
