New product： IL-6, TNF-alpha, bFGF, IFN-gamma recombinant protein upgrading!

The new product line in this recombinant protein series:

Human
IL-6 protein：Interleukin 6 (IL-6) is a pleiotropic
cytokine that plays an important role in host defense by regulating immune and
inflammatory responses. IL-6 is an important member of the cytokine network and
is central to the acute inflammatory response. After the production of IL-6, it
induces the production of C-reactive protein (CRP) and procalcitonin (PCT),
which are associated with inflammatory diseases and infections. The degree is
directly related. IL-6 can quickly diagnose early inflammation and warn of
sepsis.

Human
TNF-alpha protein：Tumor necrosis factor-α (TNF-α) is a cytokine
involved in systemic inflammation, mainly secreted by macrophages. Its main function
is to regulate immune cells. As an endogenous pyrogen, it can cause fever,
cause apoptosis, prevent tumorigenesis and virus replication. Its dysfunction
is thought to be related to many diseases, such as Alzheimer's disease,
psoriasis, cancer, major depression, and enteritis. TNF-a is an important part
of the cell signaling pathway, so it has become the target of multiple drugs.

Human
bFGF protein、Mouse bFGF protein：

Basic fibroblast growth factor (bFGF) is a trace
substance present in mammals and a multifunctional cell growth factor. bFGF has
obvious tendency activity to wound cells, induces inflammatory cells,
fibroblasts, vascular endothelial cells to move to the wound site, activates
the phagocytic function of macrophages, improves the body's immune activity,
and significantly reduces the chance of wound infection.

Human
IFN-gamma protein, His Tag、Mouse IFN-gamma protein, His Tag：IFN-gamma belongs
to the type II interferon family， which is
widely involved in immune and inflammatory responses. Proper activation of IFN-γ signaling pathway can promote the activation
of macrophages and mediate the host's defense function against pathogens. At
the same time, IFN-γ signaling
pathway can also play an immunomodulatory role in anti-tumor immunity.

How to choose appropriate Catalase (CAT) Activity Assay Kit?

Catalase (CAT) is an antioxidant enzyme commonly found in almost all living organisms. Its main function is to catalyze the decomposition of hydrogen peroxide into water and oxygen and remove hydrogen peroxide in the body, thus preventing cells from being poisoned by H₂O₂. It is one of the key enzymes in the biological defense system and provides an antioxidant defense mechanism for the body.

In this article, for CAT Activity Assay Kit, the author chose different brands (Cayman Chemical, Abcam, Biovision) and compared them with Abbkine CheKine™ Catalase (CAT) Activity Assay Kit (Cat#: KTB1040) from several aspects such as assay principle, detection, sample type and size/price.

Summary: For CAT Activity Assay Kit, the brand Abbkine and Cayman Chemical are the similar in Assay Principle. Methanol is taken as a reaction substrate. While Abcam and Biovision take H₂O₂ as a reaction substrate.

But H₂O₂ is not only a single substrate of catalase (CAT), other peroxidases in the sample may interfere with the experimental results, and the standard curve error may be caused by instability of hydrogen peroxide. While methanol is the unique substrate of catalase, other peroxidases cannot use methanol as substrate, so interference signals are avoided.

Details of different brands of products are as follows,

Brand	Assay Principle	Sample type	Size/Price
Abbkine	This assay kit utilizes the peroxidatic function of catalase for measuring catalase activity, based on the reaction of catalase with methanol, with the presence of an optimal concentration of H2O2. The formaldehyde produced can be measured colorimetrically at OD 540 nm. Therefore, the catalase activity present in the sample is proportional to the signal obtained.	Tissue Homogenate, Cell Lysate, serum, plasma, erythrocyte lysate	48T/$40 96T/$60 480T/$180
Cayman Chemical	This assay kit utilizes the peroxidatic function of catalase for measuring catalase activity, based on the reaction of catalase with methanol, with the presence of an optimal concentration of H2O2. The formaldehyde produced can be measured colorimetrically at OD 540 nm. Therefore, the catalase activity present in the sample is proportional to the signal obtained.	Tissue Homogenate, Cell Lysate, serum, plasma, erythrocyte lysate	96T/$270 480T/$490
Abcam	The catalase present in the sample reacts with hydrogen peroxide (H2O2) to produce water and oxygen. The unconverted H2O2 reacts with probe to produce a product that can be measured colorimetrically at OD 570 nm.	Serum, Plasma, Cell Lysate, Tissue Lysate, Urine	100T/$415
Biovision	The catalase present in the sample reacts with hydrogen peroxide (H2O2) to produce water and oxygen. The unconverted H2O2 reacts with probe to produce a product that can be measured colorimetrically at OD 570 nm.	Tissue Homogenate, Cell Lysate, erythrocyte lysate	100T/$340
