|Cite This Product||Alpha B Crystallin ELISA Kit (Boster Biological Technology, Pleasanton CA, USA, Catalog # EK7105)|
|Cross Reactivity||There is no detectable cross-reactivity.|
|Pack Size||96wells/kit, with removable strips.|
*Sensitivity, or Lower Limit of Detection (LLD), is the minimum level of target protein the ELISA assay can detect. We measure 20 blank wells and if the O.D. value is 2 standard deviations higher than the blanks' average O.D. the sample can be deemed positive.
|Assay Range||0.352 - 22.5 ng/ml|
*This assay range is determined using common samples. For samples with low target protein concentrations, users can adjust the standard curve to extend the lower limit of assay range.
|Sample Type||Cell lysates, Serum, Tissue|
*The above listed samples are the ones valided with the assay. If you do not see your sample of interest listed, as long as there is enough level of target protein present in the sample, this Picokine? ELISA kit should detect it.

The alpha-crystallins are major water-soluble lens structural proteins of the vertebrate eye that are related to the small heat shock protein family. The alpha-crystallins possess structural and functional similarities with HSP25 and HSP27. Mammalian lens cystallins are divided into alpha, beta and gamma families. alpha and beta families are further divided into acidic and basic groups (alpha-A and alpha-B respectively). In the lens, alpha-crystallin primarily functions to maintain proper refractive index, however it can also function as a molecular chaperone that binds to the denatured proteins, keeping them in solution and thereby maintaining the translucency of the lens. When cellular stress occurs, alpha-crystallin enters its’ phosphorylated state and may serve a structural control function and play a role in protein maintenance. In addition to their interaction with proteins, alpha-crystallins also interact with native molecules such as membrane proteins, Golgi matrix protein, structural proteins, nuclear proteins and DNA . Two other functions are an autokinase activity and participation in the intracellular architecture, and it has also been proven that both alpha-A and B prevent apoptosis by inhibiting caspases. Specifically, alpha-B cystallin is found in many cells and organs outside the lens, and alpha B is overexpressed in several neurological disorders and in cell lines under stress conditions.
