Poly-L-lysine is a positively charged amino acid polymer. Poly-lysine binds to DNA, red cell membrane and any negatively charged protein. It is typically used as a coating substrate for culture dishes, slides, etc. It enhances electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. When adsorbed to the culture surface, poly-lysine increases the number of positively charged sites available for cell binding.

The pGEX vectors have an expanded multiple cloning site (MCS) that contains six restriction sites. The expanded MCS facilitates the unidirectional cloning of cDNA inserts obtained from libraries constructed using many available lambda vectors. pGEX-6P-1, pGEX-6P-2, and pGEX-6P-3 each encode the recognition sequence for site-specific cleavage by PreScission Protease between the GST domain and the multiple cloning site. pGEX-4T-1, pGEX-4T-2, and pGEX-4T-3 are derived from pGEX-2T and contain a Thrombin recognition site. pGEX-5X-1, pGEX-5X-2, and pGEX5X-3 are derivatives of pGEX-3X and possess a Factor Xa recognition site.

Removing excess dye terminator is an essential step prior to Sanger sequencing. Carryover of the excess dye into the sequencing reactions may result in dye blobs resulting in inaccurate results. The AxyPrep™ Mag DyeClean kit utilises a paramagnetic bead-based purification system for Sanger sequencing reaction dye terminator clean-up. The protocol is simple and comprises binding, washing and elution steps which can be performed directly in the thermal cycling plate. This kit requires no centrifugation or filtration steps.

Applications
Guanidine hydrochloride can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Also used in the isolation of RNA. It is a strong chaotropic agent useful for the denaturation and subsequent refolding of protein, it can solubilize insoluble or denatured proteins such as inclusion bodies and be used for the recovery of periplasmic proteins. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Also used in the isolation of RNA.
Product Description
The crystal structure of Guanidine hydrochloride consists of a network of guanidinium cations and chloride anions linked by N–H•••Cl hydrogen bonds,it is a strong chaotropic agent.Guanidine HCl may agglomerate upon storage. It may appear as a free-flowing crystalline powder, a freeflowing powder with solid material dispersed throughout, or a solid. The quality of the product does not appear to be affected and solutions prepared from the free-flowing and lumpy guanidine HCl appear identical

The unique air distribution system combined with a finned tube evaporator results in excellent temperature consistency for biostorage: the evaporator design eliminates the risk of 'cold walls', which can damage delicate items stored touching the sides of the cabinet. Whilst the air distribution system which directs the cold air down the rear of the cabinet and back up to the evaporator fan at the top, ensures a uniform temperature throughout.
