Alkali Scientific X GAL [5 Bromo 4 chloro 3 indolyl β D galactoside], 50 Grams
Indolyl Beta-D-galactoside (50 g) is a chromogenic substrate used in gene expression assays to detect β-galactosidase activity. This substrate undergoes hydrolysis by β-galactosidase, resulting in a blue color that can be easily detected visually or quantitatively. The 50 g formulation is ideal for large-scale research applications and is widely used in studies of gene expression, cellular metabolism, and microbial activity. It is commonly used in microbiological assays, genetic research, and diagnostic applications. X-Gal is an essential tool in molecular biology for detecting and analyzing gene activity in engineered bacteria and other organisms.

Medchemexpress LLC Beta IV Tubulin Antibody (YA2267) | 50 UL
Beta IV Tubulin Antibody (YA2267) is a rabbit-derived, non-conjugated IgG monoclonal antibody that targets beta IV Tubulin. This antibody can be used as a loading control. Beta IV Tubulin is a primary component of microtubules, which are cylindrical structures formed by alpha- and beta-tubulin heterodimers. Microtubules elongate by adding GTP-tubulin dimers to their ends, creating a stabilizing cap.
- Host: Rabbit
- Isotype: IgG monoclonal antibody
- Reactivity with human, mouse, and rat samples
- Suitable for Western Blot (WB), Immunohistochemistry-Paraffin (IHC-P), Immunohistochemistry-Frozen (IHC-F), and Immunocytochemistry/Immunofluorescence (ICC/IF) applications
- Molecular weight: 50 kDa (predicted and observed)
- Storage conditions: -20°C for 1 year, avoid repeated freeze/thaw cycles
Medchemexpress LLC Inhibin beta A Antibody (YA2780) | 50 UL
The related gene encodes a member of the TGF-beta (transforming growth factor-beta) superfamily of proteins. The encoded preproprotein is proteolytically processed to generate a subunit of the dimeric activin and inhibin protein complexes. These complexes activate and inhibit, respectively, follicle stimulating hormone secretion from the pituitary gland. The encoded protein also plays a role in eye, tooth and testis development. Elevated expression of the related gene may be associated with cancer cachexia in human patients.
- Rabbit-derived IgG monoclonal antibody
- Reactivity: human, mouse, rat
- Non-conjugated
- Predicted molecular weight: 47 kDa
- Observed molecular weight: 43 kDa
- Affinity purified
- Supplied in phosphate buffered saline with BSA, sodium azide, and glycerol
- Stable for 1 year when stored at -20°C
- Liquid appearance

Alkali Scientific NPG [p Nitrophenyl β D glucuronide], 1 G
NPG (p Nitrophenyl β D Glucuronide), available in a 1g pack, is an essential reagent used for detecting glucuronidase activity in biochemical and microbiological research. The substrate, upon hydrolysis by glucuronidase enzymes, produces a yellow-colored compound that can be easily quantified, making it a critical tool for enzyme assays. NPG is commonly employed in research related to drug metabolism, liver function, and glucuronide conjugation. The 1g pack provides a larger supply for extended assays, making it ideal for high-throughput testing. This reagent is widely used in pharmaceutical and clinical laboratories for glucuronidase assays and enzyme activity studies.
