Hk2 22029 1 ap

Manufactured by Proteintech
Sourced in United States

HK2 (22029-1-AP) is a primary antibody targeted against the Hexokinase 2 (HK2) protein. Hexokinase 2 is an enzyme that catalyzes the phosphorylation of glucose to glucose-6-phosphate, a key step in glycolysis. This antibody can be used for applications such as western blotting, immunohistochemistry, and immunofluorescence to detect and study the HK2 protein.

The specific primary antibodies against E-cadherin (ET1607–75), N-cadherin (ET1607–37), snail (ER1706–22), Flag (M1403–2), p-AKT(ET1607–73), AKT (ET1609–51), p-ERK (ET1610–13), ERK (ET1601–29), p-MEK (ET1609–50), CXCR4 (ER1802–28) and ENO1 (ET1705–56) were ordered from Hangzhou Hua-An Biotechnology Company. Other antibodies included β-actin (TA-09, ZSGB-BIO), MEK (sc-436, Santa Cruz), HK2 (22029–1-AP, Proteintech), ALDOA (11217–1-AP, Proteintech) and PGK1 antibody (sc-130335, Santa Cruz).
For serum PGK1 detection, the high abundance of serum albumin and IgG was deleted [21 (link), 22 (link)] using a reagent kit following procedures (Albumin and IgG Erasin Kit, C500063–0005, Shanghai Sangon Biotechnology). Reversible Ponceau staining was used as a loading control.
The density of target band in Western blot was measured with Image J software (NIH, USA) for semi-quantification of staining signals.

Quantifying Cellular Protein Expression

Proteins present in cells and tissues were extracted utilizing the radioimmunoprecipitation lysis buffer (Beyotime). The quantification of protein concentration was accomplished using the bicinchoninic acid Protein Assay Kit (Beyotime). Subsequently, all cell lysates, each containing 40 μg protein, were subjected to SDS-PAGE and subsequently transferred onto polyvinylidene fluoride membranes through electrophoretic imprinting. The membrane was sealed with Tween-Tris buffered saline containing 5% skim milk at room temperature for a duration of 2 h. Subsequently, it was incubated with primary antibodies, namely GAPDH (2118, Cell Signaling Technology), PTMA (YN2871, Immunoway), hexokinase 2 (HK2; 22029-1-AP, Proteintech), and pyruvate kinases type M2 (PKM2; 4053, Cell Signaling Technology). Following this, the membrane containing protein bands was incubated with horseradish peroxidase-polymerized secondary antibody at room temperature for another 2 h. The imprints were visualized using the enhanced chemiluminescence detection system. The software FluorChem2.0 was employed to calculate the integral density values.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
