NH-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are joined together at a secondary amine. Terminal alkynes are reactive towards azides in copper (I) click chemistry to form stable triazoles with the target compound. The secondary amine joining the two arms can be used as a nucleophile such as in alkylation via reductive amination or in forming amides with carboxylic acids or activated NHS esters. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

Designed for those labs wishing to separate magnetic beads into rings.
The Permagen ring magnet low elution plate was designed for use in automation applications where volumes as low as 5 µL are required. Most PCR plates are bent, leading to inconsistent lab results. Unlike most products, we have added an angled frame around the top of our plate, this helps with two things, straightening out the PCR plate, and leading it to the proper location on the magnets during automation
SBS SLAS Footprint (127.75mm x 85.50mm) to fit into any automated liquid handling robot
Features include solid aluminum alloy construction and hard coat anodized finish for years of trouble-free use, and compatible with any magnetic beads

Ki-67 is a nuclear, non-histone protein that is expressed only during active phases of the cell cycle (G1, S, G2 and M), but not in the resting phases (G0 and G1 early phase). Although the antigen has also been associated with ribosomal RNA transcription, it is strongly linked to cell proliferation and has thus been indicated as an effective marker in grading the proliferation rate of tumors, including those of the brain, breast, cervix, and prostate.
