Abstract: An imaging assembly for the viewing, imaging, and analysis of chemiluminescent or bioluminescent samples in gels or other substrates, in which an adjustable camera and lens module having a prime or fixed lens or a focusing lens is moved to change the field of view by shifting the focal plane of the camera and lens module. The imaging assembly can also include a mirror to bend or fold the optical path between the camera and lens module and the target area having a sample, in which the mirror can move in the same vertical direction as the camera and lens module. Further, the camera and lens module can be configured to more move in a diagonal direction relative to the location of the imaging target area. The imaging assembly can further have a duct system adaptable to adjust with the movement of the camera and lens module.

Abstract: Disclosed herein are methods of protein quantification and normalization using haloalkylated tryptophan fluorescence. Complex protein samples, i.e., samples that each contain 1,000 or more distinct proteins, from diverse sources that do not have common protein profiles are treated with a halo-substituted organic compound (i.e. haloalkane) that reacts with tryptophan residues to form fluorescent products. Irradiation of the samples with ultraviolet light and the detection and quantification of the resultant fluorescent emissions from all proteins in each sample are then used to obtain comparative values for total protein content among the various samples. The values thus obtained are found to be valid indications of comparative total protein content, despite the fact that the tryptophan levels vary widely among the various proteins in any single sample and the samples, due to the diversity of their origins, tend to differ among themselves in the identities and relative amounts of the proteins that they contain. Protein samples are also normalized to correct for differences in sample dilution, sample loading, and protein transfer inconsistencies, by using stain-free detection of total protein in each of the samples, or detection of subsamples within each sample.

Abstract: An image system for detecting chemiluminescence in a sample uses a highly binned, short exposure initial image to calculate the exposure time for a final image of the sample. After calculation of the exposure time, at least two final images are taken, with saturated pixels removed and replaced in a first image with corresponding unsaturated pixels from a second image. The corresponding pixels are adjusted to reflect the different intensity levels between the first and second images, and the first image becomes the final image reflecting the detected chemiluminescence.

Abstract translation: 本文公开了使用卤代烷基化色氨酸荧光进行蛋白质定量和归一化的方法。 使用与色氨酸残基反应以形成荧光产物的卤素取代的有机化合物（即卤代烷）处理复合蛋白质样品，即每种含有来自不同来源的不具有共同蛋白质谱的1,000个或更多个不同蛋白质的样品。 然后使用紫外光照射样品，并对每个样品中所有蛋白质产生的荧光发射进行检测和定量，以获得各种样品中总蛋白质含量的比较值。 这样获得的值被发现是比较总蛋白质含量的有效指示，尽管事实上，任何单个样品中的各种蛋白质之间的色氨酸水平变化很大，并且样品由于其起源的多样性而趋于彼此不同 在它们所含的蛋白质的身份和相对量中。 蛋白质样品也通过使用每个样品中的总蛋白的无染色检测或每个样品中的子样品检测来校准样品稀释度，样品加载和蛋白质转移不一致性的差异。

Abstract: An imaging system including an illuminator apparatus or an epi-illumination apparatus that has LEDs for illuminations is provided for stain-free gel activation and fluorescent sample visualization. The illuminator apparatus includes a housing, a light source array disposed on at least one side surface of the housing and including at least one plurality of LEDs having each LED individually operable to output light of a predetermined color within a range of wavelengths, and a controller for controlling ranges of operational parameters of the at least one plurality of LEDs. The light emitted from the light source array incidents upon a sample having a gel that includes a product of UV light induced reaction between tryptophan and a haloalkane and the light emitted from the light source array includes ultraviolet (UV) light to excite a fluorescent response of the sample.

Abstract: Devices, systems, methods, and kits for contact imaging are provided. A contact imaging device includes an imaging sensor, a fixed fiber faceplate mechanically coupled to the imaging sensor, and an optical filtering layer mechanically coupled to the fixed fiber faceplate. The optical filtering layer can include an interference filter, an absorptive filter, and/or a removable fiber faceplate. The contact imaging device can be used to image fluorescent samples by filtering out excitation light on the basis of wavelength and/or angle of incidence.
