R-M1-8905	BSA-maleimide	BSA-maleimide is a conjugate of bovine serum albumin (BSA) and maleimide, a molecule commonly used for protein conjugation. Maleimide specifically reacts with thiol (sulfhydryl) groups present on proteins, forming a stable thioether bond. BSA-maleimide is frequently used as a carrier protein in immunology and biochemistry as it can be used to couple antigens to BSA for immunization purposes, and in biochemical assays to capture antibodies. The maleimide group allows for site-specific conjugation to proteins with exposed thiol groups, enabling the attachment of various molecules such as fluorophores, enzymes, or other haptens to BSA, expanding its applications in research.	price>
R-M-5453	IR 650 Picolyl Azide	IR 650 Picolyl Azide (IRDye® 650 Azide analog) is an advanced fluorescent probe that incorporates a copper-chelating motif to raise the effective concentration of Cu(I) at the reaction site. The rate of CuAAC reaction depends on concentrations of all reagents, including copper, thus the raise of the effective copper concentration at the reaction site dramatically increase the rate of CuAAC reaction without the need to increase concentration of azide reagent and copper.In addition, the use of IR 650 Picolyl Azide instead of conventional IR 650 Azide allows for at least a tenfold reduction in the concentration of the copper catalyst without sacrificing the efficiency of labeling.In summary, the introduction of a picolyl moiety into an azide probe leads to a substantial increase in the sensitivity of alkyne detection. This will be of special value for the detection of low abundance targets or where significant increase in signal intensity is desired.	price>
