MXD3 contains 1 basic helix-loop-helix (bHLH) domain. It is a transcriptional repressor and binds with MAX to form a sequence-specific DNA-binding protein complex which recognizes the core sequence 5'-CAC[GA]TG-3'. Antagonizes MYC transcriptional activity by competing for MAX and suppresses MYC dependent cell transformation.

B&J GC2 Solvents are developed for trace analysis at or below the part-per-billion level, using capillary gas chromatography. Each lot is performance tested to meet demanding GC specifications.

Samples of every B&J GC2 solvent are concentrated 1000-fold and tested by temperature-programmed capillary GC-FID. This analysis detects both low-boiling and high-boiling molecules, anything eluting from toluene through diesel fuel and other semi-volatile compounds of environmental interest.

Features:
Less than 1 ppb trace contamination for semi-volatiles with a molecular weight greater than toluene (92).
Ideal for EPA protocols
Actual lot chromatograms available upon request

Electron capture GC: No residue peaks greater than two ng/L as lindane.

Flame ionization GC: No peaks greater than one ng/mL, having a retention time of greater than diacetone alcohol, on a crossbonded 5% diphenyl/95% dimethyl polysiloxane capillary column for a splitless injection of a 1000-fold sample concentrate after exchange into hexane.

GABPB2 is the GA-binding protein transcription factor, beta subunit. It forms a tetrameric complex with the alpha subunit, and stimulates transcription of target genes. The encoded protein may be involved in activation of cytochrome oxidase expression and nuclear control of mitochondrial function. The crystal structure of a similar protein in mouse has been resolved as a ternary protein complex.
