Protein Extraction & Purification

BioVision's Protein Extraction and Purification Product Line contains antibiotics, cell lysis agents for bacterial cells, cell fraction kits, detergents, phosphatase and protease inhibitor cocktails, tag antibodies and protein quantitation kits. The fraction kits allow for separation of cytosolic, organellar, mitochondrial, nuclear, plasma membrane and cytoskeletal fractions. In addition, kits are included for isolation of genomic and/or mitochondrial DNA. Our detergent line includes high quality nonionic detergents (NP-40, Triton X-100, Tween-20, Tween-80, OG, OTG), a zwittergent detergents (CHAPS, ASB-14, Sulfobetaine 3-16) and an ionic detergent (SDS). The phosphatase and protease inhibitor cocktails are offered as ready to use formulations and encompass a wide variety and combinatorial forms which include both phosphatase and protease inhibitors. Our tag antibody line includes GST-, His-, HA-, S-, CBP-, DYDDDDK- and Myc-tag antibodies, while the anti-HA-tag antibodies are also offered with biotin or FITC conjugates. Finally, our protein quantification kits include both BCA-based and Bradford-type protein analysis.

Protein Quantitation Kits

Protein Quantitation Kits Products:

Protein Carbonyl Content Assay Kit (Fluorometric)   (BioVision Inc.)

Protein carbonylation occurs when chronically elevated blood sugar levels create a microenvironment for sugars to covalently react with amino acids forming non-enzymatic adducts. Oxidative stress, the excessive production of ROS, can also give rise to the production of protein carbonyls.
Protein Carbonyl Content Assay Kit   (BioVision Inc.)

Protein carbonyl groups are an important and immediate biomarker of oxidative stress. DNPH tagging of protein carbonyls has been one of the most common measures of oxidative stress. DNP hydrazones formed from the reaction are easily quantifiable at 375 nm.
His-tag Protein ELISA kit   (BioVision Inc.)

A competitve ELISA kit for the quantitative measurement of Bacterial, insect and mammalian cell lysates, downstream analyses of purification of His-tag proteins, His-tag proteins used in protein-protein interaction studies
WARNING: This product can expose you to chemicals including TMB, which is [are] known to the State of California to cause cancer. For more information go to
GST Tag ELISA Kit   (BioVision Inc.)

Ready-to-use ELISA Kit to detect as low as 45 ng/ml of GST Tag within 3 hrs.
WARNING: This product can expose you to chemicals including TMB, which is [are] known to the State of California to cause cancer. For more information go to
Extra Sense™ BCA Protein Assay Kit   (BioVision Inc.)

BioVision’s Extra Sense™ BCA Protein Assay kit provides an ultra-sensitive method to detect and quantify total protein concentration even in the presence of detergents. The Kit has been optimized for determining total protein content in low protein concentration samples (0.5-40 μg/ml).
DYKDDDDK-Tag Protein ELISA Kit   (BioVision Inc.)

A competitive ELISA kit for the fast and sensitive quantitative detection of the expressed DYKDDDDK-tag proteins.
WARNING: This product can expose you to chemicals including TMB, which is [are] known to the State of California to cause cancer. For more information go to
Biotin Quantitation Kit (Colorimetric)   (BioVision Inc.)

Biotin (Vitamin H) is an important biomolecule that has been widely used in Biotinylation reactions to label antibodies or other proteins of interest. Due to its low molecular weight, biotin usually does not cause any significant changes in protein conformation and biological activity.
BCA Protein Quantitation Kit   (BioVision Inc.)

The BCA Protein Assay Kit provides a simple, rapid, detergent tolerant (up to 5%) procedure for determining the concentration of proteins in solution. The method utilizes a copper (Cu²ᶧ) salt which can be reduced to the cuprous state by protein(s).
BCA Protein Assay Kit II   (BioVision Inc.)

Biovision’s BCA Protein Assay kit is useful for colorimetric detection and quantification of total protein content even in the presence of detergents. The BCA Protein Assay Kit is based on the chelation of bicinchoninic acid (BCA) with the cuprous cation (Cu+1), which is generated by reduction of cupric cation (Cu+2) with the protein in an alkaline medium.
