N-methyl-4-hydrazino-7-nitrobenzofurezan (MNBDH) is a new reagent for the determination of aldehydes and ketones. MNBDH reacts with carbonyl copmounds in acidic media to the corresponding MNBD-hydrazones. For example formaldehyde hydrazone formed is determined by high-performance liquid chromatography with UV/visible detection at 474 nm. MNBDH has been studied recently as a reagent with reduced interferences by ozone and nitrogen dioxide. It reacts with these oxidants to give only one product N-methyl-4-amino-7-nitrobenzofurezan (MNBDA).

A recombinant trimeric form of the HIV-1 glycoprotein (GP protein) from 16055 strain (clade C, GenBank: ABL67444.1) was produced by human embryonic kidney HEK293 cells, followed by Lectin purification. This product contains ectodomain of GP protein (end at D664) with furin cleavage site replaced by a linker, a I559P mutation for stable trimer formation, and C-terminal 8 hexa-histidine tag. This product has been evaluated by Size Exclusion Chromatography (SEC) to confirm the trimer formation, SDS-PAGE gel for purity and ELISAs for binding, see results. A rabbit antibody 11B that targets 241 glycan hole (BG505 specific, catalog U90R79) does not to bind to this protein (ref: Cell Rep. 2016;16(9):2327-38.).

3-(2-Furoyl)quinoline-2-carboxaldehyde (FQCA) is a fluorogenic derivatizing reagent for liquid chromatography suitable for high-sensitivity analysis of amino acids by laser-induced fluorescence with an argon-ion laser. The reagent forms highly fluorescent isoindoles upon reaction with primary amines. It is used for the determination of isoelectronic points (pI values) of proteins with laser-induced fluorescence detection (c-IEF-LIF). C-IEF-LIF technique can routinely detect 10-11 M of FQCA-labeled protein, compared with 10-7 M by traditional slab gel IEF and silver staining.

Glycoprotein GPVI receptor agonist. Can be used for studies on platelet receptors. Activates mammalian platelets via binding and clustering of GPVI-receptors under physiological conditions. Occupation and clustering of GPVI activates Src family kinases, phosphorylates Fc receptor gamma-chain and activates p72SYK that is critical for downstream activation of platelets. Causes cardiovascular and respiratory disturbances. Prostaglandins are strong inhibitors of convulxin-induced aggregation. Heterodimeric C-type lectin. Disulfide linked heterodimer consisting of homologous alpha and beta chains. The heterodimers are additionally linked by disulfide bridges to form cyclic alpha(4)beta(4)heterotetramers.

PNGase F PRIME is a mutant recombinant PNGase F cloned from Flavobacterium meningosepticum and expressed and purified from E. coli. The proprietary changes made to PNGase F have been shown to have unique characteristics when compared to other commercially-available sources of PNGase F. Data generated by independent labs shows that PRIME works on native glycoproteins and serum glycoproteins in minutes at room temperature. Glycan analysis of the digestion products shows that PNGase F PRIME digestion led to more complete glycan release and also allowed for the cleavage of glycans not released by the commercially-available enzymes when used at the same concentrations with the same digestion conditions. This advancement benefits applications that seek to understand glycobiology in a natural milieu. Preliminary data indicates that PNGase F PRIME has a higher specificity towards complex (tri and tetra-antennary) sialylated structures compared to the commercially sourced enzyme. Additionally, the work presented in this Analytical Chemistry paper utilized PNGase F PRIME for all in situ tissue work as the commercially-available PNGase enzymes did not work on native tissue to allow glycan recognition.
